You might say that the syntax is a superset, but the set of namespace-well-formed documents is a subset of the set of plain-old-XML-1.0-well-formed documents. As for DTDs, the original poster is right. They constrain the elements and attributes in a document by their uninterpreted names, not by their namespace name / local name pairs ("expanded names"), so they only work if you decide on the prefix in advance. There's a hack using parameter entities to make the prefix parametrizable, if you really want to. -- Richard
