Hi,

The Datatracker contains some more Comments from Ben, so here is an answer to them...

Yes and yes. The second is covered by bullet 4.

This could be said better.

Maybe 

       The Designated Experts MAY raise
       issues related to the allocation request with the 
       authors and on the IDR (or successor) mailing list
       for further consideration before the assignments
       are made.

As to the other point, the IETF has always danced around what happens when a DE says "no" and indeed what power they have to say "no". There is even the question of whether a DE can override IETF consensus -- the general opinion is that they cannot. And, in fact, the general opinion is that DEs can't say "no" because they only advice the IANA. Of course, there are angels dancing on this pinhead.

I sort of agree that more advice to the DE would be good (cos I'm a DE for this registry), but I don't know about singling out this document to pioneer giving that sort of advice.

Section 3.1 bullet 5 of RFC 7120 is the model here.

It is our pleasure to serve.
