  | Mostly, I wanted to keep the draft "chatty" because 
  | this is supposed to be a clarificiation and not a "dry" specification 
  | (countering some recommendations from Robert).

I haven't had a chance to read the new one yet (and am not currently
connected, so I can't even fetch it - didn't know it existed till I saw
this message) - but this I suspect means that we differ over what
"clarification" means.

I take it to indicate a tightly written doc which is very precise, and
makes absolutely clear any doubtful aspects of the specification being
clarified.

I would contrast that to an "explanation" which would be just fine as a
chatty doc - where the purpose is to explain why the world is the way it
is, so people understand the reasoning.

While the latter is a fine thing to have, it isn't what I think is really
needed here - that is, it isn't the crucial requirement.

  | I guess I do have one more headache - whether or not to discuss DS 
  | and NSEC types at the parent.

Is there anything about them, given their normal processing (that is,
as they are currently specified to be processed) that in any way differs
from, or complicates, the wildcard clarification?   I wouldn't have
expected so - sire they (well, DS particularly) are "different" when
it comes to normal DNS message processing, but I wouldn't have thought
that they'd affect the wildcard processing in any very peculiar way.

  | I suppose it's debate over whether this is an strict update of 1034 
  | or is an update on the concept of (1034:) wildcards.

It needs to be a clarification of the DNS as it is defined.  But it is
just a clarification, not a re-specification of everything (it isn't DNS').

   | Internet Experiment Note 116 -  Internet Name Server

I don't have a copy of the IEN's on my laptop either, so I can't go read
that (again - I'm sure I have in the past) - but I'd use care making any
use or reference at all to pre-1034 DNS related stuff, other than perhaps
to explain the historical environment (which I don't think is appropriate
in a clarifications doc).   Even 882/883 are quite different than 1034/5
when it comes to wildcards - this is an area that was changed during DNS
development.
