Gate
Connection point for relating a Message outside an InteractionFragment with a Message inside the InteractionFragment.
Gates are connected through Messages. A Gate is actually a representative of an OccurrenceSpecification that is not in the same scope as the Gate. Gates play different roles: we have formal gates on Interactions, and actual gates on InteractionUses.
