XPDL will in fact have an RDF schema.  The problem isn't just choosing a
particular schema, though.  Deciding whether to put certain types of
information about the document into the document itself or to put it in a
separate resource file is a significant issue.  It's not just the schema
vocabulary, and I don't think most people are going to be writing 'regular'
XML schemas in RDF (though it is, of course, possible.)

With a good deal of work, I'm hoping that XPDL will be able to call itself
both an RDF application and an XLink application, but still be simple
enough that creating and processing XPDs is easy.  We'll see how it goes,
of course.
