Hi,
the derivation by restriction has some constraints, for some
reference, please see the following table:
http://www.w3.org/TR/xmlschema-0/#restrictsTable and
http://www.w3.org/TR/xmlschema-1/#section-Built-in-Complex-Type-Definiti
on . You'll see that anyType has { minOccurs, maxOccurs } as { 1, 1 }
which can't be restricted.
Cheers
