-- TEST OBJECTIVE:
-- Check that an extended type can be derived in the specification of a
-- generic package when the parent is an abstract type in a library
-- package.

-- Extend an abstract type in the visible part of a generic package.
-- Make all of the procedures which override abstract procedures
-- available as part of the generic interface. Instantiate the generic.
--
-- TEST FILES:
-- This test depends on the following foundation code:
--
-- F393B00.A Package Alert_Foundation
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
