-- OBJECTIVE:
--      Check that the functionality found in packages Ada.Strings.Wide_Maps,
--      Ada.Strings.Wide_Bounded, and Ada.Strings.Wide_Maps.Wide_Constants 
--      is available and produces correct results.
--
-- TEST DESCRIPTION:
--      This test tests the subprograms found in the 
--      Ada.Strings.Wide_Bounded package.  It is based on the tests
--      CXA4027-28, which are tests for the complementary "non-wide" 
--      packages.
--      
--      The functions found in CXA4029_0 provide mapping capability, when
--      used in conjunction with Wide_Character_Mapping_Function objects.
--
--       
-- CHANGE HISTORY:
--      23 Jun 95   SAIC    Initial prerelease version.
--      18 Apr 96   SAIC    Incorporated reviewer comments for ACVC 2.1.
