RDF documents can be sent around just like any other XML documents.

I don't know that that means. RDF should be used as a way of
documenting the metadata used in a "form" or some other xml document.
This can be used to validate the data, if needed. It provides more than
a DTD does in that it allows one to describe the semantics of the
information. How that maps to "buttons" is beyond me.
