I hope I answered this in more detail in a message I just sent off. There's no definition in XML that allows for well-formed content *within* valid content. Either the entire document is valid or its not. DTDs cannot deal with only part of the content being checked. I'm not even sure if XML Schema can do this. If so, you *could* use the XML Schema for XHTML being developed within the HTML WG to validate the XHTML, and some sort of module to allow for the RDF to be validated. But my understanding is that even XML Schema can't validate generic RDF. I keep maintaining that RDF is too low a level a syntax to be validated by any type of schema, since it's not really an application but more a higher level grammar than XML than it is really a "markup language".
