Description

Enumeration and fixed/default values are exposed from simple types and element/attribute declarations. Element/attribute values are also available in PSVI. But the way they are exposed is not very clear, and information about the member type used for list of union types is not available.

We need to introduce a new interface that represents a "value", which has all the information about the value. Then this new "value" can be returned from simple types, declarations, and PSVI.

We also need to expose Identity Constraint definitions from XSModel and XSNamespaceItem, because they are, in a sense, global. This at least makes it easier for SCD implementation.
