-- TEST OBJECTIVE:
--      Check that an extended type can be derived from an abstract type
--      when that derivation is declared in a child package.
--
-- TEST DESCRIPTION:
--      Add a visible child to Alert_Foundation.  Using the abstract type
--      Alert as parent, declare an extended type with discriminant and new
--      record components.  Override the Handle procedure.
--  
-- TEST FILES: 
--      This test depends on the following foundation code:
--
--         F393B00.A  Package Alert_Foundation
--
--
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--      15 Oct 95   SAIC    Fixed bugs for ACVC 2.0.1
