<P>
SchemaType is an interface implemented by all schema types: simple and complex types, built-in and
user-defined types.
<p>There is a hierarchy of interfaces that extend SchemaType, representing the top levels of the schema
type system: SimpleType and ComplexType, with SimpleType further subdivided into List, Union, and Atomic
types.</p>
<p>The implementations of these interfaces are organized into a different hierarchy: on the one side,
built-in types such as AnyType, AnySimpleType, and the built-in atomic types and list types; on the other
side, user-defined types defined in a schema.</p>
