For XHTML one would use the rdf:XMLLiteral.

This example of RDFa is confusing. The presence of xml:base seems to
mean this is an XML document (XHTML? No namespace is given) however
it's using the rdf:HTML type for it's content. I have no idea what the
result of that should be :D xml:base is the least of worries in this
case.
