+--     PARTICULAR PURPOSE OF SAID MATERIAL.
+--*
+--
+-- OBJECTIVE:
+--      Check that, for an inherited dispatching operation that is overridden,
+--      the body executed is the body of the overriding subprogram, even if
+--      the overriding occurs in a private part.
+--
+--      Check for the case where the overriding operation is declared in a
+--      separate (non-child) package from that declaring the parent type, and
+--      the descendant type is a record extension.
+--
+--      Check for both dispatching and nondispatching calls.
+--
+-- TEST DESCRIPTION:
+--      Consider:
+--
+--      package P is
+--         type Root is tagged ...
+--         procedure Op (A: Root);
+--      end P;
+--
+--      with P;
+--      package Q is
+--         type Derived1 is new P.Root with record...
+--         -- Implicit procedure Op (A: Derived1) declared here.
+--         type Derived2 is new P.Root with private...
+--         -- Implicit procedure Op (A: Derived2) declared here.
+--         type New_Derived is new Derived1 with private...
+--         -- Implicit procedure Op (A: New_Derived) declared here.
+--      private
+--         procedure Op (A: Derived1);  -- Overrides parent's Op.
+--         type Derived2 is new P.Root with record...
+--         procedure Op (A: Derived2);  -- Overrides parent's Op.
+--         type New_Derived is new Derived1 with record...
+--         ...
+--      end Q;
+--
+--      Both type Derived1 and Derived2 inherit Op from the parent type Root. 
+--      Type New_Derived inherits (inherited) Op from Derived1.  The inherited 
+--      operation is implicitly declared immediately after the type extension.  
+--      The inherited operation is overridden by an explicit declaration in 
+--      the private part. Even though the overriding operation is private, 
+--      calls to Op with an operand of tag Derived1, Derived2, or New_Derived
+--      will execute the body of the overriding operation.
