+--*
+--
+-- OBJECTIVE:
+--      Check that a nonprivate tagged type declared in a package specification
+--      may be extended with a record extension in a different package
+--      specification, and that this record extension may in turn be extended
+--      by a private extension in a third package.
+--  
+--      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 record 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.
+--      
+--      Extend the extension with a private extension in a third package
+--      specification. Declare a new primitive subprogram for this private
+--      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.
+-- 
+--      Also in the third package, declare two operations of the private
+--      extension which utilize aggregates and equality operators to verify
+--      the correctness of the components.
+--
+--      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 using aggregates and equality
+--      operators, or by checking the components directly, or, for the private
+--      extension, by calling the verification operations declared in the
+--      third package.
