--
-- OBJECTIVE:
--    Check that operational items are allowed in some contexts where
--    representation items are not:
--
--       1 - Check that the name of an incompletely defined type can be used
--           when specifying an operational item. (RM95/TC1 7.3(5)).
--
--       2 - Check that operational items can be specified for a descendant of
--           a generic formal untagged type. (RM95/TC1 13.1(10)).
--
--       3 - Check that operational items can be specified for a derived
--           untagged type even if the parent type is a by-reference type or
--           has user-defined primitive subprograms. (RM95/TC1 13.1(11/1)).
--
--    (Defect Report 8652/0009, as reflected in Technical Corrigendum 1).
--
-- CHANGE HISTORY:
--    19 JAN 2001   PHL   Initial version.
--     3 DEC 2001   RLB   Reformatted for ACATS.
--     3 OCT 2002   RLB   Corrected incorrect type derivations.
