If you want every XML system to understand a schema, then you need a different model. You need a single VERY simple core schema language that all XML 1.2 (say) validating processors are *required* to understand, and make it extensible. Otherwise one person will use SQL, another tcl, another LISP s-exprs, another PROLOG Horn Clauses, and there will be no interoperability. And XML is all about inteoperability. The XML Stylesheet declaration, by the way, should have been done with XLink. The fact that an XML document does not use the XML linking mechanism for links to its DTD and components indicates a problem. In our case, the problem is that XLink wasnt invented, of course.
