starting with this moinwiki on /my_page:

moinwiki_in.Converter.call ->

   <moin_page:page>
     <moin_page:body>
       <moin_page:p>
         <xinclude:include xhtml:alt="photo" xhtml:width="80%" xinclude:href="wiki.local:/photo.jpg?" />
       </moin_page:p>
     </moin_page:body>
   </moin_page:page>

content.Content.internal_representation adds page_href to the top level element:

   <moin_page:page moin_page:page-href="wiki:///my_page">
     <moin_page:body>
       <moin_page:p>
         <xinclude:include xhtml:alt="photo" xhtml:width="80%" xinclude:href="wiki.local:/photo.jpg?" />
       </moin_page:p>
     </moin_page:body>
   </moin_page:page>

content._expand_document

\_include.Converter.call converts xinclude:include to moin_page.object with moin_page.type and xlink:href, retaining the xinclude:href
- \_ mark_item_as_transclusion adds data_href and xhtml:class to the moin_page

   <moin_page:page moin_page:page-href="wiki:///my_page">
     <moin_page:p>
       <moin_page:page moin_page:page-href="wiki:///my_page/photo.jpg" xhtml:class="moin-transclusion" xhtml:data-href="/my_page/photo.jpg">
         <moin_page:body>
           <moin_page:object moin_page:type="image/jpeg" xhtml:alt="photo" xhtml:width="80%" xlink:href="wiki:///my_page/photo.jpg?do=get&amp;rev=521f309c038c4ce7b8670371ac60335b" xinclude:href="wiki.local:/photo.jpg?">my_page/photo.jpg</moin_page:object>
