      <t>This document describes the change extension mapping for version 1.0 of the 
      Extensible Provisioning Protocol (EPP).  This mapping, an extension of the domain 
      name mapping described in <xref target="RFC5731" format="default"/>, and an extension of the host mapping described 
      in <xref target="RFC5732" format="default"/>, is specified using the Extensible Markup Language (XML) 1.0 as described 
      in <xref target="W3C.REC-xml-20040204"></xref> and XML Schema notation as described in <xref target="W3C.REC-xmlschema-1-20041028"></xref> and

        "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
        "OPTIONAL" in this document are to be interpreted as described in
        <xref target="BCP14"/> when, and only when, they appear in all capitals, as
        shown here.</t>
        <t>In examples, "C:" represents lines sent by a protocol client and "S:"
        represents lines returned by a protocol server.  Indentation and white
        space in examples is provided only to illustrate element relationships
        and is not a REQUIRED feature of this specification.</t>
        <t>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.</t>
        <t>The XML namespace prefix "changeExt" is used for the namespace
        "http://www.verisign-grs.com/epp/changeExt-1.0", but implementations MUST NOT
        depend on it; instead, they should employ a proper namespace-aware
        XML parser and serializer to interpret and output the XML documents.</t>

		  <t>The EPP &lt;create&gt; command provides a transform operation that allows a client 
		  to create a domain or host object.  In addition to the EPP command elements described 
		  in [EPP-D] and [EPP-H], the command MAY contain an &lt;extension&gt; element.  The 
		  &lt;extension&gt; element MUST contain a child &lt;changeExt:changeExt&gt; element that contains 
		  the following child elements:</t> 
		  <ul spacing="normal">
		   <li><t>A &lt;changeExt:requestID&gt; element that MUST contain a request identifier, defined in section 2.1,
