     flood-message = [M_FLOOD, session-id, initiator, ttl,
                     +[objective, (locator-option / [])]]

You added the +[] there so that we can announce multiple objectives.
I don't think that there is anything more to do in GRASP.

All we need to do is define the AN_Proxy objective, and ACP has to
define the AN_ACP objective.  I just don't see any problem here.
