The plain fact is that the XML schema specs are logically contradictory when one thinks of a value space as a set. Enquires have determined that XMLSchema value spaces are not sets, but something like categories or algebras. The same thing, seen as a member of two different value spaces, is considered to be two different things. This is simply impossible in RDFS if we interpret value spaces as classes. So I was trying to give the reader a warning about this without being so coarse as to imply anything derogatory about XML schema. > >4. ><<suggest-delete>> >[[Implementors who wish to check any kind ... >backchaining on the clousre rules, for example.]] > >(any normative suggestions about impl techniques may degrade the >value of others) > Done. >That's it - no more comments at this stage. OK. Many thanks. Right now Ive finished fixing the proofs (they read much better now) and am working on the boilerplate, references, etc. Pat -- --------------------------------------------------------------------- IHMC (850)434 8903 home 40 South Alcaniz St. (850)202 4416 office Pensacola (850)202 4440 fax FL 32501 (850)291 0667 cell phayes@ai.uwf.edu http://www.coginst.uwf.edu/~phayes s.pam@ai.uwf.edu for spam
