The point is that XSC:Doc has controlled content, and that content is IBTWSH elements (which may contain non-IBTWSH elements via the new parameter entity "ibtwsh.include"). IBTWSH being by intention HTML-compatible, and HTML having no prefixes, IBTWSH elements shouldn't appear with prefixes either. Allowing a different "xmlns" attribute value in XSC:Doc would mean that (e.g.) a P element would *not* be an IBTWSH P, but semantically some other P altogether, while still being required to conform (by the XSchema DTD) to the content model and attribute list declarations of an IBTWSH P. > I don't see any reason the same URN can't > be used twice, and end up equivalent. If it's kosher, it's going in. URN should be URI here and below. URI means: <!ENTITY URI "URL or URN"> :-) > There are other fun things we could do, like adding an attribute to > XSC:XSchema elements that identifies the namespace in which they live via the > URN (forget the prefix), After mulling it for several days, I think this is the Right Thing. Add an #IMPLIED "ns" attribute to ElementDecl and AttDef elements whose value is an URI. XSchema validation can then proceed with respect to the actual URIs, and disregarding the actual prefixes used in particular documents. This gives XSchemas a leg-up on DTDs, which are bound to specific prefixes in the name of SGML (and XML 1.0) compatibility. -- John Cowan http://www.ccil.org/~cowan cowan@c... You tollerday donsk? N.
