Unfortuantely, the RDF model theory does not (yet) provide an acceptable
account of RDF semantics.  The current RDF model theory WD (of 14 February
2002) only provides an account for N-triples, and is missing other features
of RDF.

In particular, there is no treatment of RDF reification or RDF containers
in the current RDF model theory.  The current RDF model theory also does
not consider datatypes or the new thinking on RDF literals.  Finally, the
translation from RDF/XML to N-triples is performed outside this model
theory, and this translation is quite complex.
