To specify restriction, a generalization must be used between this class and a super class. This generalization either has or does not have the XSDrestriction stereotype. Restriction id and annotation maps to Generalization properties.

In order to have an inner simpleType element, the parent of this Generalization must be the inner Class of the outer UML Class.
