--
-- OBJECTIVE
--     Check that an others choice is allowed in an array aggregate whose
--     applicable index constraint is dynamic. (This was an extension to
--     Ada 83). Check that index choices are within the applicable index
--     constraint for array aggregates with others choices.
--
-- TEST DESCRIPTION
--     In this test, we declare several unconstrained array types, and
--     several dynamic subtypes. We then test a variety of cases of using
--     appropriate aggregates. Some cases expect to raise Constraint_Error.
