For people inventing languages which use Qnames in element or attribute values, I commend making your own prefix->namespace declaration element instead of piggybacking on the XML namespaces system. That way you can have sanity: namespace must have prefix, prefix cannot be remapped or reused, no default namaspace. I did this in Schematron without significant trouble. The XML Namespaces rec does not cover Qnames in values: that is semantics that is up to the schema developer. XSLT does it one way, XML Schemas does it another way, and Schematron does it another.
