 * A TypeURI provides the unique identity of a type which is a unique concept for type checking.
 * The most common but not only form of a type is an EClass. Since we may also have UML
 * Classes and Pivot Classes and user defined types, we use a TYpeURI to provide the flexibility.
 * <p>
 * The TypeURI is computed from the namespace URI.
