I think we also need a completeness indicator, so you can 
say 'this is the complete set of my outgoing MTAs or
these are member of the set of my outgoing MTAs'.

OK, I'll bite. What's the advantage in listing only a proper subset?

If there is an authorization mechanism in place at the receiver
end you can still take the benefit of accreditation even though
you might not be able guarantee that you were able to list out
every one of your legitimate edge email servers.


Right, but wouldn't a "wildcard" or universal record (with an accreditation
modifier) give you the same benefit?
Or even a "bare" accreditation assertion? (empty set)
  
What am I missing here?
