XML Schema can't, Eric van der Vlist spent a long time trying each of DTDs, XML Schema, RELAX, and Schematron, and later TREX for validating some of the "looser" but commonly expected modular extensions to RSS. *Just* RSS, which has constraints even further than RDF alone. That may be exactly the problem with extent XML specs, there is no spec that allows for well-formed (or seperately validated) content within valid content. I think this problem would be easily solved once the realization is made that that is *exactly* what we are asking for in several applications of XML. -- Ken
