-- OBJECTIVE:
--    Check that objects designated by X'Access (where X is of a class-wide
--    type) and new T'Class'(...) are dynamically tagged and can be used in
--    dispatching calls.  (Defect Report 8652/0010).
--
-- CHANGE HISTORY:
--    18 JAN 2001   PHL   Initial version
--    15 MAR 2001   RLB   Readied for release.
--    03 JUN 2004   RLB   Removed constraint for S0, as the subtype has
--                        unknown discriminants.
