While it is o.k. to have the rdf and foaf namespaces copied into the generated XML Literal, the xmlns="http://www.w3.org/1999/xhtml" is actually incorrect. In the case of XHTML1 this namespace indeed appears in the file, can therefore be copied into the XMLLiteral, ie, that test is o.k. for XHTML1+RDFa, that namespace does *not* appear for HTML5, ie, it should not be added to the XML Literal. We can create a separate test for HTML5+RDFa, doing the same but with a different SPARQL. On the other hand, in view of the controversial nature of the xmlns usage in HTML5, I would probably be o.k. to remove it from the HTML5 branch altogether. I am not sure about XHTML5. Does the namespace appears for that one? If so, it is fine to have it for that one...
