 * Checks constraints that apply to various complex properties of GML objects.

 * temporal objects, and location descriptions.
 * 
 * Implicit property type definitions are examined to ensure they have valid
 * content models, since invalid type derivations (i.e. restrictions of existing
 * GML property types) should be detected when the application schema is
 * initially assessed for XML Schema compliance.
