I've gone through everyone's (wonderful) comments and have addressed
almost all of them, and published a -10.  Please let me know if you
think I missed anything.  Responses to the comments will be sent out
shortly.

(and sorry for the delay on this ; day-job hit me over the head hard in
the last three weeks )

Two outstanding topics:

1) A number of people have suggested adding references to other
RFCs/documents to many of the error codes.  This is probably a good
idea.  A beer or other drink in Singapore to anyone willing to do the
work to give me a list of references to add for each code.

2) One outstanding topic of discussion that I think we need to decide to
handle or table till a future document: how do we handle forwarding,
chained resolvers, and caching.  Puneed brought this up most recently in
his comments.  In the past we've pseudo-agreed that it will be rather
complex to document how to handle forwarding, etc, when some of the
error context will change upon a forward, for example.  IE,
forwarding/caching/whatever rules may end up being code specific and may
require a *lot* more thought.  So, IMHO, we have choices:

A) Label these situations as "undefined behavior" and define it in a
future document after we get more experience with deployment.  This is
typically where I've landed opinion-wise in the past, and still do
mostly now.

B) Document globally how to handle various cases (and we'll need to
enumerate them)

C) Document how to handle each one independently (or as an override if
needed to a global policy)

D) Your option here

So really, this first comes down to how important is it we handle this
case set before it goes out the door?
