I totally agree with Jim's comments here.  The integration of XML Schema
datatypes into DAML+OIL was done because we needed them and RDF didn't
support them.  When RDF comes up with a decent solution to this problem,
perhaps by adapting the solution we have devised for DAML+OIL, I, 
for one, will happily convert to that solution.

Further, I would be more than happy to help the RDF working group in this
