Are XML schemas to recognize the fact that one of the things done with XML is to represent data that has a different information set (than that of XML instances)? This is not very clearly addressed in the Requirements document. The language of the charter seems to ignore this issue. Usage Scenario 7 strongly suggests such recognition, by calling out particular metadata standards that are about data of non-XML information sets. I also find Usage Scenario 6 suggests such recognition to me (e.g., it suggests I might use an XML schema as a new kind of IDL and map it into various programming languages, getting not a DOM but the kinds of types one finds in that language --- records, arrays, unions, and so on). If such a recognition is indeed made, it seems (to me) to be appropriate to consider conceptually organizing the content of an XML schema so that one can view it as containing types for the data of the other information sets, as well as for their representations in XML. No such thing currently appears in the draft requirements list. Mike Spreitzer <spreitze@parc.xerox.com> http://www.parc.xerox.com/spreitze/ +1-650-812-4833
