 * This file contain definitions of the valuetypes and interfaces of
 * Supports_Test, a test of TAO's OBV capabilities. Specifically, Supports_Test
 * checks proper operation of the following features:
 *
 * -Valuetypes that support concrete interfaces:
 *    Using the same valuetype implementation, Supports_Test creates both
 *    valuetypes and object references, passes them as parameters, and
 *    invokes both local and remote calls.
 * -ORB::register_value_factory () return values:
 *    Supports_Test checks the return values of register_value_factory () to
 *    ensure compliance with the spec.
