>See design issue 42 - we need to add the case where the superType is a transient class (non-entity & non-mappedSuperclass) - we leave it as null in this as well (since the superType must be an IdentifiableType - and therefore persistent) http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/metamodel_api#DI_42:_20090709:_IdentifiableType.supertype_-_what_do_top-level_types_set_it_to
