Even though each schema document may only work with one namespace you can of course make a schema for a multi-namespace "document type" (or "MIME type") by using inclusions. I'll also note that the W3C is having a discussion on a highly related issue. What is the relationship between mime types (AKA Internet document types) and namespaces. Simon's recent publication indicates that he thinks that namespaces are semantically meaningful enough to be a good trigger for processing. Of the two solutions you present, I think I prefer the document-centric one because it allows people to use namespaces however they want, as they have in the past. XSLT would be radically different if it was forced to fit a model wherein embedded namespaces must be purely the same as if they were in a standalone document. In general, I'm not convinced that that is a feasible approach. It is just too useful to be able to add features to subordinate namespaces. Plus, it is easier to add a concept of "document type" than to retroactively deprecate uses of namespaces that are not pure. If a particular combination of namespaces happens to be pure then the meta-schema and meta-stylesheet that glues them together should be trivial to write. Paul Prescod
