<h2>IPTC Extension schema</h2>
<p>This schema specifies the IPTC Extension XMP properties. The IPTC
   Extension schema extends and complements the IPTC Core schema by a set
   of more granular properties and further specialized rights related
   properties from the PLUS metadata schema.
 <ul>
  <li>Exiv2 keys are <b><code>Xmp.iptcExt.&lt;Property&gt;</code></b></li>
  <li>The schema namespace URI is <b><code>http://iptc.org/std/Iptc4xmpExt/2008-02-29/</code></b></li>
  <li>The preferred schema namespace prefix is <b><code>Iptc4xmpExt</code></b></li>
 </ul>
Reference: <a href="http://www.iptc.org/std/photometadata/specification/IPTC-PhotoMetadata" title="IPTC Extension Specification Version 1.2">IPTC Extension Specification Version 1.2</a> standard</p>
<p>Note: Exiv2 uses <b><code>iptcExt</code></b> (rather than <code>Iptc4xmpExt</code>) as the group name for keys of IPTC Extension schema properties.</p>
