--
-- OBJECTIVE:
--      Check that formal parameters of a class-wide type can be passed 
--      values of any specific type within the class.
--
-- TEST DESCRIPTION:
--      Define an object of a root tagged type and of various types derived
--      from the root.  Define objects of the root class, and initialize them
--      by parameter association of objects of the specific types (root and 
--      extended types) within the class.
--
--      The particular root and extended types used in this abstraction are
--      defined in foundation code (F341A00.A), and are graphically displayed
--      as follows:
--
--           package Bank
--              type Account
--                  |
--                  |
--                  |
--               package Checking
--                  type Account
--                      |
--                      |
--                      | 
--                   package Interest_Checking
--                          type Account
--
