But after sending it I noticed that you referred to a schema rather than a schema document. And at the risk of being pedantic about a difference which the spec regards as important and many users appear not to regard as important at all, I write to point out that as regards schemas, the presupposition of your question is in error. XSD schemas have always had the ability to include components in multiple namespaces -- indeed, almost all schemas are multi-namespace schemas, since any user-defined schema will typically include components (elements, types, ...) in the user's target namespace, and will also include all the built-in datatypes in the XSD namespace. -- **************************************************************** * C.
