That's definitely true.  I think it's an important point that's lost in
this discussion a bit.  The debate should be RDF's model vs. XML's
model.  There are a whole lot more semantics involved with RDF's model
than XML's model.  So application developers should think about not
which serialization to choose, but which data model to choose.  I think
RDF wins out here, with a very rich data model.  I look at XML's model
and I think "so what?".  It gives my application more simple parsing,
that's it.  With RDF, my application is able to work with a data model
with rich semantics.  And, of course, adding ontological data adds even
more semantics.  I can mix ontologies a lot easier than I can mix DTD's.
