--

-- 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
