+-- OBJECTIVE:
+--      Check that if the type of the ancestor part of an extension aggregate
+--      has discriminants that are not inherited by the type of the aggregate,
+--      and the ancestor part is a subtype mark that denotes a constrained
+--      subtype, Constraint_Error is raised if: 1) any discriminant of the
+--      ancestor has a different value than that specified for a corresponding
+--      discriminant in the derived type definition for some ancestor of the
+--      type of the aggregate, or 2) the value for the discriminant in the
+--      record association list is not the value of the corresponding 
+--      discriminant.  Check that the components of the value of the
+--      aggregate not given by the record component association list are
+--      initialized by default as for an object of the ancestor type.
+--
+-- TEST DESCRIPTION:
+--      Consider:
+--
+--      type T (D1: ...) is tagged ...
+--
+--      type    DT is new T with ...
+--      subtype ST is DT (D1 => 3);    -- Constrained subtype.
+--
+--      type NT1 (D2: ...) is new DT (D1 => D2) with null record;
+--      type NT2 (D2: ...) is new DT (D1 => 6)  with null record;
+--      type NT3           is new DT (D1 => 6)  with null record;
+--
+--      A: NT1 := (T  with D2 => 6); -- OK: T  is unconstrained.
+--      B: NT1 := (DT with D2 => 6); -- OK: DT is unconstrained.
+--      C: NT1 := (ST with D2 => 6); -- NO: ST.D1 /= D2.
+--
+--      D: NT2 := (T  with D2 => 4); -- OK: T  is unconstrained.
+--      E: NT2 := (DT with D2 => 4); -- OK: DT is unconstrained.
+--      F: NT2 := (ST with  . . . ); -- NO: ST.D1 /= DT.D1 as specified in NT2.
+--
+--      G: NT3 := (T  with D1 => 6); -- OK: T  is unconstrained.
+--      H: NT3 := (DT with D1 => 6); -- OK: DT is unconstrained.
+--      I: NT3 := (ST with D1 => 6); -- NO: ST.D1 /= DT.D1 as specified in NT3.
+--
+--      In A, B, D, E, G, and H the ancestor part is the name of an
+--      unconstrained subtype, so this rule does not apply. In C, F, and I
+--      the ancestor part (ST) is the name of a constrained subtype of DT,
+--      which is itself a derived type of a discriminated tagged type T. ST
+--      constrains the discriminant of DT (D1) to the value 3; thus, the
+--      type of any extension aggregate for which ST is the ancestor part
+--      must have an ancestor which also constrained D1 to 3. F and I raise
+--      Constraint_Error because NT2 and NT3, respectively, constrain D1 to
+--      6. C raises Constraint_Error because NT1 constrains D1 to the value
+--      of D2, which is set to 6 in the record component association list of
+--      the aggregate.
+--
+--      This test verifies each of the three scenarios above:
+--
+--         (1) Ancestor of type of aggregate constrains discriminant with
+--             new discriminant.
+--         (2) Ancestor of type of aggregate constrains discriminant with
+--             value, and has a new discriminant part.
+--         (3) Ancestor of type of aggregate constrains discriminant with
+--             value, and has no discriminant part.
+--
+--      Verification is made for cases where the type of the aggregate is
+--      once- and twice-removed from the type of the ancestor part.
+--      
+--      Additionally, a case is included where a new discriminant corresponds
+--      to multiple discriminants of the type of the ancestor part.
+--
+--      To test the portion of the objective concerning "initialization by 
+--      default," the test verifies that, after a successful aggregate
+--      assignment, components not assigned an explicit value by the aggregate
+--      contain the default values for the corresponding components of the
+--      ancestor type.
+--

+-- CHANGE HISTORY:
+--      06 Dec 94   SAIC    ACVC 2.0
+--      15 Dec 94   SAIC    Removed discriminant defaults from tagged types.
+--      17 Nov 95   SAIC    ACVC 2.0.1 fixes: Corrected subtype constraint
+--                          for component NT_C3.Str2. Added missing component
+--                          checks. Removed record component update from
+--                          Avoid_Optimization. Fixed incorrect component
+--                          checks.
+--      02 Dec 95   SAIC    ACVC 2.0.1 fixes: Corrected Failed comment for
+--                          Q case.
