I, similarly, find some stuff in XML Schema, including some in XML Schema datatypes, that is not completely laudable. As an academic it would be totally appropriate for me, or some group of like-minded people, to propose a completely different mechanism for providing typed data for XML. However, as a group that is working within the W3C, I think that the RDF Core working group should be extremely cautious of providing something counter to XML Schema datatypes. I know that the people who have been putting together DAML+OIL have tried extremely hard to maintain compatability with other W3C efforts, even though we are not part of W3C, even when many of us have felt that there were technically better ways to proceed, and even during this time when I feel that our efforts are not being supported very well by the W3C process. Should not the members of the RDF Core WG, who are much more closely tied to W3C, expend even more effort to obtain compatability between RDF and other W3C efforts? In closing let me mention one potential ramification of divergance between RDF and other W3C efforts. If RDF does not follow other W3C efforts, then why should other groups, such as the DAML+OIL people, follow RDF? Peter F. Patel-Schneider
