-- OBJECTIVE:
--      Check that a nonprivate tagged type declared in a package specification
--      may be extended with a private extension in a different package
--      specification, and that this private extension may in turn be extended
--      by a private extension.
--
--      Check that each derivative inherits the user-defined primitive
--      subprograms of its parent (including those that its parent inherited),
--      that it may override these inherited primitive subprograms, and that it
--      may also declare its own primitive subprograms.
--
--      Check that predefined equality operators are defined for the tagged
--      type and its derivatives.
--
--      Check that type conversion is defined from a type extension to its
--      parent, and that this parent itself may be a type extension.
--
-- TEST DESCRIPTION:
--      Declare a root tagged type and two associated primitive subprograms
--      in a package specification (foundation code).
-- 
--      Extend the root type with a private extension in a different package
--      specification. Declare a new primitive subprogram for the extension,
--      and override one of the two inherited subprograms. Within the
--      overriding subprogram, utilize type conversion to call the parent's
--      implementation of the same subprogram. Also within the overriding
--      subprogram, call the new primitive subprogram and each inherited
--      subprogram. Declare operations of the private extension which utilize
--      aggregates and equality operators to verify the correctness of the
--      components.
--      
--      Extend the extension with a private extension in the same package
--      specification. Declare a new primitive subprogram for this second
--      extension, and override one of the three inherited subprograms.
--      Within the overriding subprogram, utilize type conversion to call the
--      parent's implementation of the same subprogram. Also within the
--      overriding subprogram, call the new primitive subprogram and each
--      inherited subprogram. Declare operations of the private extension
--      which override the verification operations of its parent. Within
--      these overriding operations, utilize type conversion to call the
--      parent's implementations of the same operations.
-- 
--      In the main program, declare objects of the two extended types.
--      For each object, call the overriding subprogram, and verify the
--      correctness of the components by calling the verification operations
--      declared in the second package.
