<section anchor="introduction" title="Introduction">
<t> Service providers and enterprises use registries to make
call or session routing decisions for Voice over IP, SMS and
MMS traffic exchanges. This document is narrowly focused on
the provisioning protocol for these registries. This protocol
prescribes a way for an entity to provision session-related
data into a registry. The data being provisioned can be
optionally shared with other participating peering entities.
The requirements and use cases driving this protocol have been
documented in <xref
target="I-D.ietf-drinks-usecases-requirements"/>. The reader
is expected to be familiar with the terminology defined in the
previously mentioned document. <vspace blankLines="1"/> Three
types of provisioning flows have been described in the use
case document: client to registry provisioning, registry to
local data repository and registry-to-registry. This document
addresses a subset (client-to-registry provisioning) by
defining a Session Peering Provisioning Protocol (SPPP) for
provisioning Session Establishment Data (SED) into a Registry
(arrow "1" in the figure below). While the other "provisioning
flows" are shown below as separate message flows, no
determination has been made for whether one common baseline
protocol could be used for all three, or whether distinct
protocols are required. </t>

<postamble> Three Registry Provisioning Flows </postamble>
</figure>
</t>
<t> The data provisioned for session establishment is typically
used by various downstream SIP signaling systems to route a
call to the next hop associated with the called domain. These
systems typically use a local data store ("Local Data
Repository") as their source of session routing information.
More specifically, the SED data is the set of parameters that
the outgoing signaling path border elements (SBEs) need to
initiate the session. See <xref target="RFC5486"/> for more
details. <vspace blankLines="1"/> A "terminating" SIP Service
Provider (SSP) provisions SED into the registry to be
selectively shared with other peer SSPs. Subsequently, a
Registry may distribute the provisioned data into local Data
Repositories used for look-up queries (identifier -> URI) or
for lookup and location resolution (identifier -> URI ->
ingress SBE of terminating SSP). In some cases, the Registry
may additionally offer a central query resolution service (not
shown in the above figure). </t>
<t> A key requirement for the SPPP protocol is to be able to
accommodate two basic deployment scenarios: <list
style="numbers">
<t> A Local Data Repository serves a Look-Up Function (LUF) to determine the target domain
to assist in call routing (as described in <xref
target="RFC5486"/>). In this case, the querying entity
may use other means to perform the Location Routing
Function (LRF) which in turn helps determine the actual
location of the Signaling Function in that domain. </t>
<t> A Local Data Repository serves both a Look-Up function (LUF) and Location Routing
Function (LRF) to locate the SED data fully. </t>
</list>
</t>
<t> In terms of protocol design, SPPP protocol is agnostic to
the transport. This document includes the description of the
data model and the means to enable protocol operations within
a request and response structure. To encourage
interoperability, the protocol supports extensibility aspects. </t>
<t> Transport requirements are provided in this document to help
with the selection of the optimum transport mechanism. (<xref
target="I-D.ietf-drinks-sppp-over-soap"/>) identifies a SOAP
transport mechanism for SPPP. </t>

<t> SPPP can be viewed as a set of layers that collectively
define the structure of an SPPP request and response. Layers
1 and 2, as detailed below, are left to separate
specifications to allow for potentially multiple SPPP
transport, envelope, and authentication technologies. This
document defines layers 3, 4, and 5 below. </t>
<t>
<list style="numbers">
<t> The transport protocol layer provides a communication
mechanism between the client and server. SPPP can be
layered over any transport protocol that provides a set
of basic requirements defined in the Transport Protocol

<t> The message envelope layer is optional, but can
provide features that are above the transport technology
layer but below the application messaging layer.

<postamble> SPPP Data Model </postamble>
</figure>
<t> The objects and attributes that comprise the data model
can be described as follows (objects listed from the
bottom up): <list style="symbols">
<t> Public Identifier: <vspace blankLines="0"/>
A public identifier is a well known
attribute that is used as the key to perform lookup
functions. For the purposes of this document, a Public
Identifier can be a telephone number, a range of telephone
numbers, a PSTN Routing Number (RN), or perhaps another
type of lookup key. <vspace blankLines="1"/> A Public
Identifier may be associated with a Destination Group to
create a logical grouping of Public Identifiers that share a common set of
Routes. <vspace blankLines="1"/> A Public Identifier
may optionally be associated with zero or more
individual Route Records. This ability for a Public
Identifier to be directly associated with a set of Route
Records (e.g. target URI), as opposed to being
associated with a Destination Group, supports the use
cases where the target URI contains data specifically
tailored to an individual Public Identifier. </t>
<t> Telephone Number Range: <vspace blankLines="0"/>
A public identifier may represent
an inclusive range of telephone numbers. The TN range
is defined by the first and last telephone number of
the inclusive range. For example, a TN range defined by
tn=12125550000 and endTn=12125560000 means all the TNs
from 12125550000 to 12125560000 inclusive are included. </t>
<t> Destination Group: <vspace blankLines="0"/>
A name collection of zero or more Public Identifiers that
can be associated with one or more Route Groups for the
purpose of facilitating the management of thier common
routing information. </t>
<t> Route Group: <vspace blankLines="0"/>
A Route Group contains a set of references to Route Records,
a set of Destination Group references, and a set of
peering organization identifiers. This is used to
establishe a three part relationships between a set of
Public Identifiers and their common routing information
(SED), and the list of peering organizations whose query
responses may include that routing information in their
query responses. To support the use cases defined in
[I-D.ietf-drinks-usecases-requirements], this document
defines the following types of Route Records: NAPTRType,
NSType, and URIType. The sourceIdent element within a Route
Group, in concert with the set of peering organization
identifiers enables fine grained source based routing.
Further details about the Route Group and source based routing
refer to the definitions and descriptions of the Route
Group operations found later in this document. </t>
<t> Route Record: <vspace blankLines="0"/>
A Route Record contains the data that a resolution system
returns in response to a successful query for a Public
Identifier. Route Recoords are associated with a Route
Group for SED that is not specific to a Public Identifier.
<vspace blankLines="0"/> To support the use cases defined in
<xref target="I-D.ietf-drinks-usecases-requirements"/>,
SPPP protocol defines three type of Route Records:
URIType, NAPTRType, and NSType. These Route Records
extend the abstract type RteRecType and inherit the
common attribute 'priority' that is meant for setting
precedence across the route records defined within a
Route Group in a protocol agnostic fashion. </t>
<t> Organization: <vspace blankLines="0"/> An
Organization is an entity that may fulfill any
combination of three roles: Registrant, Registrar, and
Peering Organization. All SPPP objects are
associated with two organization identifiers to identify
each object's registrant and the registrar. A Route Group
object is also associated with a set of zero or more
organization identifiers that identify the peering
organizations whose query responses may include the
routing information (SED) defined in the Route Records
within that Route Group. </t>
</list>
</t>
</section>
</section>
<section anchor="transportreq" title="Transport Protocol Requirements">
<t> This section provides requirements for transport protocols
suitable for SPPP. More specifically, this section specifies
the services, features, and assumptions that SPPP delegates to
the chosen transport and envelope technologies. </t>
<t> Two different groups of use cases are specified in <xref
target="I-D.ietf-drinks-usecases-requirements"/>. One group
of use cases describes the provisioning of data by a client
into a Registry (Section 3.1 of the above referenced
document), while the other group describes the distribution of
data into local data repositories (Section 3.2). The current
version of this document focuses on the first set of use cases
(client to registry provisioning). <vspace blankLines="1"/>
These use cases may involve the provisioning of very small
data sets like the modification or update of a single public
identifier. Other provisioning operations may deal with huge
datasets like the "download" of a whole local number
portability database to a Registry. <vspace blankLines="1"/>
As a result, a transport protocol for SPPP must be very
flexible and accommodate various sizes of data set sizes. </t>
<t> For the reasons outlined above, it is conceivable that
provisioning and distributing may use different transport
protocols. This document focuses on the provisioning protocol. </t>
<t>A few topics remain open for discussion: <list
style="symbols">
<t>The ability to establish multiple connections between a
client and server may be desirable. If so, we may want to
specify the relation of transactions between the various
connections.</t>
<t>Pipelining of requests is required at the SPPP protocol
layer. It may have impacts at the transport level that
need to be outlined.</t>
<t>Scope: the current scope of this effort is based upon
having a connection oriented transport. Is there any need
to support a transport protocol with asynchronous
operation? </t>
<t>If it is required that responses arrive in the order of
the requests, this must be specified clearly.</t>
</list>
</t>
<section anchor="transpconnreq" title="Connection Oriented">
<t> The SPPP protocol follows a model where a Client
establishes a connection to a Server in order to further
exchange provisioning transactions over such point-to-point
connection. A transport protocol for SPPP MUST therefore be
connection oriented. </t>
<t> Note that the role of the "Client" and the "Server" only
applies to the connection, and those roles are not related
in any way to the type of entity that participates in a
protocol exchange. For example, a Registry might also
include a "Client" when such a Registry initiates a
connection (for example, for data distribution to SSP). </t>
</section>
<section anchor="requestresponse"
title="Request and Response Model">
<t> Provisioning operations in SPPP follow the request -
response model, where a transaction is initiated by a Client
using a Request command, and the Server responds to the
Client by means of a Response. <vspace blankLines="1"/>
Multiple subsequent request-response exchanges MAY be
performed over a single connection. </t>
<t> Therefore, a transport protocol for SPPP MUST follow the
request-response model by allowing a response to be sent to
the request initiator.</t>
</section>
<section anchor="connectionlength" title="Connection Lifetime">
<t> Some use cases involve provisioning a single request to a
network element - connections supporting such provisioning
requests might be short-lived, and only established on
demand. </t>
<t> Other use cases involve either provisioning a huge set of
data, or a constant stream of small updates, which would
require long-lived connections. </t>
<t> Therefore, a protocol suitable for SPPP SHOULD support
short lived as well as long lived connections. </t>
</section>
<section anchor="authentication" title="Authentication">
<t> Many use cases require the Server to authenticate the
Client, and potentially also the Client to authenticate the
Server. While authentication of the Server by the Client is
expected to be used only to prevent impersonation of the
Server, authentication of the Client by the Server is
expected to be used to identify and further authorize the
Client to certain resources on the Server. </t>
<t> Therefore, an SPPP transport protocol MUST provide means
for a Server to authenticate and authorize a Client, and MAY
provide means for Clients to authenticate a Server. </t>
<t> However, SPPP transport SHOULD also allow for
unauthenticated connections. </t>
</section>
<section anchor="confidentiality"
title="Confidentiality and Integrity">
<t> Data that is transported over the protocol is deemed
confidential. Therefore, a transport protocol suitable for
SPPP MUST ensure confidentiality and integrity protection by
providing encryption capabilities. </t>
<t> Additionally, a DRINKS protocol MUST NOT use an unreliable
lower-layer transport protocol that does not provide
confidentiality and integrity protection. </t>
</section>
<section anchor="timing" title="Near Real Time">
<t> Many use cases require near real-time responses from the
Server. Therefore, a DRINKS transport protocol MUST support
near-real-time response to requests submitted by the Client.
</t>
</section>
<section anchor="respsizes" title="Request and Response Sizes">
<t> SPPP covers a range of use cases - from cases where
provisioning a single public identifier will create very
small request and response sizes to cases where millions of
data records are submitted or retrieved in one transaction.
Therefore, a transport protocol suitable for SPPP MUST
support a great variety of request and response sizes. </t>
<t> A transport protocol MAY allow splitting large chunks of
data into several smaller chunks. </t>
</section>
<section anchor="reqorder"
title="Request and Response Correlation">
<t> A transport protocol suitable for SPPP MUST allow
responses to be correlated with requests. </t>
</section>
<section anchor="ack" title="Request Acknowledgement">
<t> Data transported in the SPPP protocol is likely crucial
for the operation of the communication network that is being
provisioned. <vspace blankLines="1"/> Failed transactions
can lead to situations where a subset of public identifiers
(or even SSPs) might not be reachable, or situations where
the provisioning state of the network is inconsistent. </t>
<t> Therefore, a transport protocol for SPPP MUST provide a
Response for each Request, so that a Client can identify
whether a Request succeeded or failed. </t>

data structures for most of the supported operations and object types.
This section describes these common data structures.</t>

<t> The data elements within the <![CDATA[<spppUpdateRequest>]]>
element are described as follows:
<list style="symbols" hangIndent="5">
<t> clientTransId: Zero or one client generated transaction ID
that, within the context of the SPPP client, identifies this
request. This value can be used at the discretion of the SPPP
client to track, log or correlate requests and their responses. This
value is also echoed back to the client in the SPPP update response.
An SPPP server will not check this value for uniqueness. </t>
<t> minorVer: Zero or one minor version identifier, indicating the minor
version of the SPPP API that the client is attempting to use. This is
used in conjunction with the major version identifier in
the XML namespace to identify the version of SPPP that the client
is using. If the element is not present, the server assumes that
the client is using the latest minor version supported by the SPPP
server for the given major version. The versions supported by a
given SPPP server can be retrieved by the client using the
SPPP server menu operation described later in the document.</t>
<t> rqst: One or more BasicRqstType objects. These are the actions
that the client is requesting the SPPP server perform. They are processed
by the SPPP server in the order in which they are included in the request.
And with respect to handling error conditions, it is a matter of policy
whether the objects are processed in a "stop and rollback" fashion or
in a "stop and commit" fashion. In the "stop and rollback" scenario,
the SPPP server would stop processing BasicRqstType object instances in the
request at the first error and roll back any BasicRqstType object instances
that had already been processed for that update request.
In the "stop and commit" scenario the SPPP server would stop
processing BasicRqstType object instances in the request at the
first error but commit any BasicRqstType object instances
that had already been processed for that update request.

<section anchor="addrtegrp" title="Add Route Group Operation">
<t> As described in the introductory sections, a Route Group
represents a combined grouping of Route Records that define
route information, Destination Groups that contain a set of
Public Identifiers with common routing information, and the
list of peer organizations that have access to these public
identifiers using this route information. It is this
indirect linking of public identifiers to their route
information that significantly improves the scalability and
manageability of the peering data. Additions and changes to
routing information are reduced to a single operation on a
Route Group or Route Record , rather than millions of data updates
to individual public identifier records that individually contain
their peering data. </t>

Group object. If a Route Group with the given

<t>The RteGrpType object is composed of the following
elements: <list style="symbols" hangIndent="5">
<t> base: All first class objects extend
BasicObjType which contains the ID of the
registrant organization that owns this object, the ID
of the registrar organization that provisioned this
object, the date and time that the object was created
by the server, and the date and time that the object
was last modified. If the client passes in either the
created date or the modification date, the server will
ignore them. The server sets these two date/time values.</t>
<t> rteGrpName: The character string that contains the
name of the Route Group. It uniquely identifies this
object within the context of the registrant ID (a child
element of the base element as described above). </t>
<t> rteRecRef: Set of zero or more objects of type RteRecRefType
that house the unique keys of the Route Records that the
the RteGrpType object refers to and their relative priority
within the context of a given route group. The associated Route
Records contain the routing information, sometimes called SED,
associated with this Roue Group.</t>
<t> dgName: Set of zero or more names of DestGrpType
object instances. Each dgName name, in association with
this Route Group's registrant ID, uniquely identifies a
DestGrpType object instance whose public identifiers are
reachable using the routing information housed in this
Route Group. An intended side affect of this is that
a Route Group cannot provide routing information for a
Destination Group belonging to another registrant. </t>
<t> peeringOrg: Set of zero or more peering organization
IDs that have accepted an offer to receive this Route
Group's information. The set of peering organizations in
this list is not directly settable or modifiable using
the addRteGrpsRqst operation. This set is instead
controlled using the route offer and accept operations. </t>
<t> sourceIdent: Set of zero or more SourceIdentType
object instances. These objects, described further
below, house the source identification schemes and
identifiers that are applied at resolution time as part
of source based routing algorithms for the Route Group. </t>
<t> isInSvc: A boolean element that defines whether this
Route Group is in service. The routing information
contained in a Route Group that is in service is a
candidate for inclusion in resolution responses for
public identities residing in the Destination Group
associated with this Route Group. The routing
information contained in a Route Group that is not in
service is not a candidate for inclusion in resolution
responses. </t>
<t> priority: Zero or one priority value that can be used
to provide a relative value weighting of one Route Group
over another. The manner in which this value is used,
perhaps in conjunction with other factors, is a matter of
policy.</t>
<t> ext: Point of extensibility described in a previous
section of this document. </t>
</list>
</t>
<t> As described above, the Route Group contains a set of references
to route record objects. A route record object is based on an
abstract type: RteRecType. The concrete types that use
RteRecType as an extension base are NAPTRType, NSType, and
URIType. The definitions of these types are included the Route
Record section of this document. </t>
<t> The RteGrpType object provides support for source-based
routing via the peeringOrg data element and more granular
source base routing via the source identity element. The
source identity element provides the ability to specify zero or
more of the following in association with a given Route
Group: a regular expression that is matched against the
resolution client IP address, a regular expression that is
matched against the root domain name(s), and/or a regular
expression that is matched against the calling party URI(s).
The result will be that, after identifying the visible Route
Groups whose associated Destination Group(s) contain the
lookup key being queried and whose peeringOrg list contains
the querying organizations organization ID, the resolution server
will evaluate the characteristics of the Source URI, and Source
IP address, and root domain of the lookup key being queried.
The resolution server then compares these criteria against the
source identity criteria associated with the Route Groups. The
routing information contained in Route Groups that have
source based routing criteria will only be included in the
resolution response if one or more of the criteria matches
the source criteria from the resolution request. The Source
Identity data element is of type SourceIdentType, whose structure
is defined as follows:</t>

<section anchor="pubIdsOper" title="Public Identifier Operations">
<t>Public Identifier is the search key used for locating the session establishment data (SED). In many cases, a Public Identifier is attributed to the end user who has a retail relationship with the service provider or registrant organization. In SPPP, SED can be provisioned by the registrant, or by the registrar on behalf of the registrant. Also, SPPP supports the notion of the carrier-of-record as defined in RFC 5067. Therefore, the entity adding the Public Identity in the Registry can optionally claim to be a carrier-of-record.</t>
<t>SPPP identifies three types of Public Identifiers: telephone number (TN), email address, and the routing number (RN). SPPP also supports the requirement of adding a contiguous range of TNs including the length variance associated to the Open Number Plan.</t>
<t>The XML schema type definition PubIDType is the generalization of the Public Identifier. PubIDType is an abstract type. In agreement with the data model, PubIDType member 'dgName' represents the name of the destination group that a given Public Identifier is associated to. The PubIDType object structure is defined as follows:</t>

</t>
<t>A registrant can add a Public Identifier with the help of a BasicRqstType called AddPubIdRqstType. To complete the add request, AddPubIdRqstType XML instance is added to <spppUpdateRequest> root element. If there is a conflict and a Public Identifier already exists in the Registry, the old entry will be replaced with the newly provisioned entry. For the add or update operation, the destination group name is a mandatory parameter. Not including a valid destination group name in the update request will cause the Registry to return an appropriate error.</t>
<t>Telephone number is identified by TNType, an extension of PubIDType. TNType is composed of the following attributes:
<list style="symbols" hangIndent="5">
<t>tn: Telephone number to be added to the Registry.</t>
<t>rteRecRef: Optional reference to the route record that is directly associated with the TN Public Identifier. Following the SPPP data model, the route record could be a protocol agnostic URIType or another type.</t>
<t>corInfo: corInfo is an optional parameter of type CORInfoType that allows the registrant organization to set forth a claim to be the carrier-of-record [see RFC 5067]. This is done by setting the <corClaim> element of the CORInfoType object structure to true. The other two parameters of the CORInfoType, <cor> and <corDateTime> are meant to be set by the Registry to relay the outcome of the carrier-of-record claim by the registrant. In general, inclusion of <corInfo> parameter is useful if the Registry has the authority information, such as, the number portability, etc., in order to qualify whether the registrant claim can be satisfied. If the carrier-of-record claim disagrees with the authority data of the Registry, whether the TN add operation fails or not is a matter of policy and it is beyond the scope of this document. In the response message <spppUpdateResponse>, the SPPP Server must include the <cor> parameter of the <corInfo> element to let the registrant know the outcome of the claim.</t>

If the Registry encounters an error in adding even a single TN that is part of the TN range, the whole request will be deemed a failure. In other words, the TNRType add request is transactional in nature, and the partial success case is not supported.</t>

Next, the originating SSP can add the egress route in the Registry, with appropriate regular expression, to rewrite ingress route information from the target SSP and include the egress SBE information. In high-availability configurations, the originating SSP will likely add a secondary egress route object re-writing the same ingress route from the target SSP with a secondary choice of egress SBE as a backup.

<t> As described in the introductory sections, a Route Group
represents a combined grouping of Route Records that define
route information. However, Route Records need not be created to
just server a single Route Group. Route Records can be created
and managed to serve multiple Route Groups. As a result, a change
to the properties of a network node, for example, that is used for
multiple routes, would necessitate just a single update operation

<t> As described above, route records are based on an
abstract type: RteRecType. The concrete types that use
RteRecType as an extension base are NAPTRType, NSType, and
URIType. The definitions of these types are included below.
The NAPTRType object is comprised of the data elements
necessary for a NAPTR that contains routing information for a
Route Group. The NSType object is comprised of the data
elements necessary for a Name Server that points to another
DNS server that contains the desired routing information.
The URIType object is comprised of the data elements
necessary to house a URI. </t>
<t> The data provisioned in a Registry can be leveraged for
many purposes and queried using various protocols including
SIP, ENUM and others. It is for this reason that a route
record type offers a choice of URI and DNS resource record
types. URIType fulfills the need for both SIP and ENUM protocols. When a given URIType is associated to a destination group, the user part of the replacement string <uri> that may require the Public Identifier cannot be preset. As a SIP Redirect, the resolution server will apply <ere> pattern on the input Public Identifier in the query and process the replacement string by substituting any back reference(s) in the <uri> to arrive at the final URI that is returned in the SIP Contact header. For an ENUM query, the resolution server will simply return the value of the <ere> and <uri> members of the URIType in the NAPTR REGEX parameter.</t>

<section anchor="getrterecs" title="Get Route Records Operation">
<t> The getRteRecsRqst operation allows a client to get the
properties of Route Record objects that a registrar
organization is authorized to view. The server will attempt
to find a Route Record object that has the registrant ID and
route record name pair contained in each ObjKeyType object
instance. If the set of ObjKeyType objects is empty then the
server will return the list of Route Record objects that the
querying client has the authority to view. If there are no
matching Route Record found then an empty result set will be
returned. </t>
<t> The element passed into the spppQueryRequest element for this
operation is an instance of type GetRteRecsRqstType, which
extends BasicRqstType and contains zero or more ObjKeyType
objects. Any limitation on the maximum number of objects that
may be passed into or returned by this operation is a policy
decision and not limited by the protocol. The XSD declaration
of the operation is as follows: </t>

<t>This section shows XML message exchange between two SIP Service Providers (SSP) and a Registry. For the sake of simplicity, the transport wrapper for the SPPP protocol is left out. The SPPP protocol messages in this section are valid XML instances that conform to the SPPP schema version within this document.</t>
<t>In this sample use case scenario, SSP1 and SSP2 provision resource data in the registry and use SPPP constructs to selectively share the route groups. In the figure below, SSP2 has two ingress SBE instances that are associated with the public identities that SSP2 has the retail relationship with. Also, the two SBE instances for SSP1 are used to show how to use SPPP protocol to associate route preferences for the destination ingress routes and exercise greater control on outbound traffic to the peer's ingress SBEs.</t>

<t>In order for SSP1 to complete session establishment for a destination TN where the target subscriber has a retail relationship with SSP2, it first requires an asynchronous bi-directional handshake to show mutual consent. To start the process, SSP2 initiates the peering handshake by offering SSP1 access to its route group.</t>

<t> XML serves as the encoding format for SPPP, allowing complex
hierarchical data to be expressed in a text format that can be
read, saved, and manipulated with both traditional text tools
and tools specific to XML. <vspace blankLines="1"/> XML is
case sensitive. Unless stated otherwise, XML specifications
and examples provided in this document MUST be interpreted in
the character case presented to develop a conforming
implementation. <vspace blankLines="1"/> This section
discusses a small number of XML-related considerations
pertaining to SPPP. </t>
<section anchor="namespaces" title="Namespaces">
<t> All SPPP protocol elements are defined in the namespaces
in te IANA Considerations section and in the Formal Protocol
Specification section of this document.
</t>
</section>
<section anchor="versioning" title="Versioning and Character Encoding">
<t> All XML instances SHOULD begin with an
<![CDATA[ <?xml?> ]]> declaration to identify the version of
XML that is being used, optionally identify use of the
character encoding used, and optionally provide a hint to an
XML parser that an external schema file is needed to
validate the XML instance. <vspace blankLines="1"/>
Conformant XML parsers recognize both UTF-8 (defined in
<xref target="RFC3629"/>) and UTF-16 (defined in <xref
target="RFC2781"/>); per <xref target="RFC2277"/> UTF-8 is
the RECOMMENDED character encoding for use with SPPP. </t>
<t> Character encodings other than UTF-8 and UTF-16 are
allowed by XML. UTF-8 is the default encoding assumed by XML
in the absence of an "encoding" attribute or a byte order
mark (BOM); thus, the "encoding" attribute in the XML
declaration is OPTIONAL if UTF-8 encoding is used. SPPP
clients and servers MUST accept a UTF-8 BOM if present,
though emitting a UTF-8 BOM is NOT RECOMMENDED. </t>
