The problem you are facing is a common misunderstanding that people face with dealing with derivation by restriction in W3C XML Schema. Your derivation breaks the following rule Schema Component Constraint: Particle Restriction OK (Elt:Elt -- NameAndTypeOK) For an element declaration particle to be a ¡¤valid restriction¡¤ of another element declaration particle all of the following must be true: 1 The declarations' {name}s and {target namespace}s are the same. -- PITHY WORDS OF WISDOM If at first you don't succeed, imitate.
