I don't see how your document forbids nodes labeled with literals as the
heads of edges.  As you make the RDF graphs be your primary syntax, I think
that you have to allow all RDF graphs, not just RDF graphs that derive from
valid XML serializations (or valid sequences of n-triples).

My suggestion would be to change your definition of RDF graphs.  (See also
my upcoming message on a cleaned-up model theory for RDF.)
