Actually, trading partners invariably require more than validity. Validity does NOT ensure conformance to "an agreed on DTD". A document is valid if it conforms to any old DTD that it happens to reference. This is a real practical problem because most XML parsers don't give you an easy way of validating an incoming document against a specific DTD. Michael Kay
