--
-- OBJECTIVE:
--      Check that the full type completing a type with no discriminant part
--      or an unknown discriminant part may have explicitly declared or
--      inherited discriminants.
--      Check for cases where the types are records and protected types.
--
-- TEST DESCRIPTION:
--      Declare two groups of incomplete types: one group with no discriminant 
--      part and one group with unknown discriminant part.  Both groups of 
--      incomplete types are completed with both explicit and inherited 
--      discriminants.  Discriminants for record and protected types are 
--      declared with default and non default values.
--      In the main program, verify that objects of both groups of incomplete 
--      types can be created by default values or by assignments.
--
--
-- CHANGE HISTORY:
--      11 Oct 95   SAIC    Initial prerelease version.
--      11 Nov 96   SAIC    Revised for version 2.1.
