Here is the essence of your problem: There is no way to say "any element other than x, y or z in any namespace" in XML Schema. You can say "any element in any namespace", "any element in a specific list of namespaces", "any element not in the target namespace". There are no expressions for exclusionary constraints by element name. What you want is a kind of cooccurrence constraint. Most cooccurrence constraints on validity must be enforced some way other than XML Schema validation (either using Relax NG or a some other validation scheme like Schematron or in the application code). For example, you cannot express in XML Schema that the attribute x must have a value at least 10 greater than the value of attribute y.
