"unused namespace" is still a largely undefined term, so it's not clear that the question means anything, but mixing dtds and namespaces is fraught with problems. In particular any use of namespaces with different prefixes would be schema valid but dtd invalid (unless you change the dtd to match). Also, because "unused" isn't defined I can't tell whether or not the following document which is dtd valid is an instance of a dtd failing to detect if the namespace is used. <!DOCTYPE x [ <!ELEMENT x EMPTY> <!ATTLIST x xmlns:foo CDATA #IMPLIED> ]> <x xmlns:foo="bar"/> David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
