  61 This interface is implemented by elements that are able to do XMP serialization. Examples for
  62 such elements are <span class="type">jifmux</span> and <span class="type">qtmux</span>.
  63 </p>
  64 <p>
  65 Applications can use this interface to configure which XMP schemas should be used when serializing
  66 tags into XMP. Schemas are represented by their names, a full list of the supported schemas can be
  67 obtained from <a class="link" href="gst-plugins-base-libs-gsttagxmp.html#gst-tag-xmp-list-schemas" title="gst_tag_xmp_list_schemas ()"><code class="function">gst_tag_xmp_list_schemas()</code></a>. By default, all schemas are used.
