+-- 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

+-- CHANGE HISTORY:
+-- 06 Dec 94 SAIC ACVC 2.0
