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 effort.
