How does the proposal to define the primary syntax for OWL in XML bring us
any closer to going outside this part of our charter?  After all, the
primary syntax for RDF is (still) defined in XML.

I believe that several problems with DAML+OIL have already been pointed
out, and some better solutions have been proposed.  In particular, the
proposal by Michael Smith alludes to one of these problems.  So again, how 
does the proposal take us any further out of our charter?
