 * TYPEDEF: SRM_Object_Reference
 *
 *  An Object_Reference is an opaque non-object data type
 *  that allows an application to reliably access an instance
 *  of an object. Object_References may be compared for
 *  equality and tested to see if they are equal to the
 *  special value NULL_Object. If two Object_References are
 *  equal, they refer to the same object instance. In all
 *  the method specifications in the API clause of
 *  18026, whenever an argument passed to or returned from a
 *  method is an object, it is an object reference that is
 *  passed.
