   Re: [xml-dev] Problem designing complexType accepting a specified elemen

[ Lists Home | Date Index | Thread Index ]

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.
