--*
-- OBJECTIVE:
-- Check that objects of types with a specified Default_Component_Value are
-- appropriately initialized.
--
-- Part 4: Generic arrays of real types.
--
-- TEST DESCRIPTION:
-- We assume that if a programmer cares to define a Default_Component_Value
-- for a type, they care that objects of the type are properly initialized
-- in any possible context. Thus, we do not attempt to define a particular
-- usage scenario.
--
-- The test types are declared in a foundation package in order to model a
-- more realistic usage.
--
-- We test for initialization in the following contexts:
-- (A) Stand-alone objects;
-- (B) Default initialized components;
-- (C) <> initialization in array and record aggregates;
-- (D) Allocators.
--
-- CHANGE HISTORY:
-- 30 Sep 2020 RLB Created test for RRS, donated to ACATS.
