-- 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
