26-- OBJECTIVE:
27--      For a type extension, check that predefined equality is defined in
28--      terms of the primitive equals operator of the parent type and any
29--      tagged components of the extension part.
30--
31--      For other composite types, check that the primitive equality operator
32--      of any matching tagged components is used to determine equality of the
33--      enclosing type.
34--
35--      For private types, check that predefined equality is defined in
36--      terms of the user-defined (primitive) operator of the full type if
37--      the full type is tagged. The partial view of the type may be
38--      tagged or untagged. Check that predefined equality for a private
39--      type whose full view is untagged is defined in terms of the
40--      predefined equality operator of its full type.
41--
42-- TEST DESCRIPTION:
43--      Tagged types are declared and used as components in several
44--      differing composite type declarations, both tagged and untagged.
45--      To differentiate between predefined and primitive equality
46--      operations, user-defined equality operators are declared for
47--      each component type that is to contribute to the equality
48--      operator of the composite type that houses it. All user-defined
49--      equality operations are designed to yield the opposite result
50--      from the predefined operator, given the same component values.
51--
52--      For cases where primitive equality is to be incorporated into
53--      equality for the enclosing composite type, values are assigned
54--      to the component type so that user-defined equality will return
55--      True. If predefined equality is to be used instead, then the
56--      same strategy results in the equality operator returning False.
57--
58--      When equality for a type incorporates the user-defined equality
59--      operator of one of its component types, the resulting operator
60--      is considered to be the predefined operator of the composite type.
61--      This case is confirmed by defining an tagged component of an
62--      untagged composite type, then using the resulting untagged type
63--      as a component of another composite type. The user-defined operator
64--      for the lowest level should still be called.
65--
66--      Three cases are set up to test private types:
67--
68--                        Case 1        Case 2      Case 3
69--         partial view:  tagged       untagged    untagged
70--         full view:     tagged        tagged     untagged
71--
72--      Types are declared for each of the above cases and user-defined
73--      (primitive) operators are declared following the full type
74--      declaration of each type (i.e., in the private part).
75--
76--      Values are assigned into objects of these types using the same
77--      strategy outlined above. Cases 1 and 2 should execute the
78--      user-defined operator. Case 3 should ignore the user-defined
79--      operator and user predefined equality for the type.
