-- DESCRIPTION:
--     This package provides tailorable entities for a particular
--     implementation.  Each entity may be modified to suit the needs
--     of the implementation.  Default values are provided to act as
--     a guide.
--
--     The entities in this package are those which are used in at least
--     one core test. Entities which are used exclusively in tests for
--     annexes C-H are located in annex-specific child units of this package.

--                         specific child packages. Adjusted commentary.
--                         Renamed Validating_System_Programming_Annex to
--                         Validating_Annex_C. Added similar Validating_Annex_?
--                         constants for the other non-core annexes (D-H).
