    <section title="Introduction">
      <t>The <xref target="RFC5102">RFC5102</xref>, section 4, defines the IPFIX Information Elements in the range of 1-127 to be compatible with the Netflow version 9 fields, as defined in the <xref target="RFC3954">RFC3954</xref>. This document describes some of the fields that are being used, but which appeared later than the <xref target="RFC3954">RFC3954</xref> was published.</t>
