--
-- OBJECTIVE:
--      Check that structures nesting discriminated records as
--      components in record extension are correctly supported.  Check
--      for this using limited private structures.
--      Check that record extensions inherit all the visible components
--      of their ancestor types. 
--      Check that discriminants are correctly inherited.
--
-- TEST DESCRIPTION:
--      This test defines a textbook object, a serial number plaque.
--      This object is used in each of several other structures modeled
--      after those used in an existing antenna modeling software system.
--      Record types discriminated and undiscriminated are nested to
--      produce a layered design.  Some parametrization is programmatic;
--      some parametrization is data-driven.
--
--
--
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--      19 Dec 94   SAIC    Removed RM references from objective text.
--      19 Apr 95   SAIC    Added "limited" to full type def of "Object"
