--
-- TEST OBJECTIVE:
-- Check that an extended type can be derived in a private child package
-- from an abstract type defined in a library package.
--
-- TEST DESCRIPTION:
-- Add a private child package to Alert_Foundation. Using Private_Alert
-- as parent type, declare an extended type adding a new record component.
-- Override procedure Handle. Declare an object of the new type in the
-- child specification. Use type definitions from the private part of the
-- parent in the body of the child.
--
-- TEST FILES:
-- This test depends on the following foundation code:
--
-- F393B00.A Package Alert_Foundation
