The problem is that you've used the wrong namespace for XML Schema: in particular from http://www.daml.org/2001/03/daml+oil-ex-dt.xsd <xsd:schema xmlns:xsd ="http://www.w3.org/2000/10/XMLSchema#"> this.. umm... looks like an XML Schema but isn't. The XML Schema namespace does not end with a '#'. There are no two ways about this, the W3C XML namespace recommendation states that namespace names are to be compared by literal string comparison and something as simple as a single character difference makes the namespaces different. Yep, the fact that the XML Schema namespace URI ends in a 'a' rather than a '#' causes a problem integrating RDF and XML Schema datatypes, but doing what you are doing just glosses over the problem. -JonathanReceived on Wednesday, 28 March 2001 19:39:30 GMT
