CORBA23 — Does the DII support the standard object operations?

Summary: There are two types of standard operations: ones that are transmitted
over the wire, and ones that are not. Now it seems reasonable to
support the over-the-wire operations via the DII, such as "is_a",
"non_existent", "get_interface" and "get_implementation" (obsolete), but
what about the ones that don"t go over the wire:

hash
is_equivalent
get_policy
get_domain_managers

I would guess that the DII should not support these operations, but the
spec does not explicitly say that. So, should we add a statement to the
DII part of the spec that an attempt to invoke these non-over-the-wire
operations should raise BAD_OPERATION?
