26-- OBJECTIVE
27--     Check that an others choice is allowed in an array aggregate whose
28--     applicable index constraint is dynamic. (This was an extension to
29--     Ada 83). Check that index choices are within the applicable index
30--     constraint for array aggregates with others choices.
31--
32-- TEST DESCRIPTION
33--     In this test, we declare several unconstrained array types, and
34--     several dynamic subtypes. We then test a variety of cases of using
35--     appropriate aggregates. Some cases expect to raise Constraint_Error.
