-- TEST OBJECTIVE:
--      Check that an extended type can be derived from an abstract type.
--
-- TEST DESCRIPTION:
--      Declare an abstract type in the specification of a generic package.
--      Instantiate the package and derive an extended type from the abstract
--      (instantiated) type; override all abstract operations; use all
--      inherited operations;
--

-- CHANGE HISTORY:

--      14 Oct 95   SAIC    Fixed for ACVC 2.0.1
