Quite.  I (personally - this is not a NI view) regard OWL as a useful
language in its own right for exchanging models.  The RDF part is, for
me, a by-product of the fact that W3C is specifying OWL, rather than a
necessity, and so I am pleased to see an OWL/XML encoding.  However, I'm
aware that I'm probably in a minority in this WG on that one!

From NI's point of view, I believe NI has some customers who prefer
OWL/RDF and others who prefer OWL/XML - and, indeed, others to whom OWL
is irrelevant as they just want a way of interfacing to a sound and
complete reasoner for a well-defined language.  Unfortuinately, I'm not
at liberty to state what the proportions are.
