+--
+-- TEST OBJECTIVE:
+-- Check that an extended type can be derived from an abstract type,
+-- where the abstract type is defined in a package, and the type derived
+-- from it is defined in a distinct library package.
+--
+-- TEST DESCRIPTION:
+-- Declare an private (abstract) type; declare two primitive operations
+-- of the type that are explicitly abstract.
+-- Derive an extended type from the (private) abstract type, overriding
+-- both of the primitive operations.
+-- This test also checks to see that name overloading between abstract
+-- and non-abstract functions is resolved correctly.
