I do not understand this point.  Having now read both IDs, I see
relevant points for the ongoing discussion in both of them.   I see them
as complementary where both contribute to defining the problem in a
comprehensive way.

I think it would make sense to ask the authors to combine their efforts,
that being a first step in finding consensus on how to proceed -
otherwise the back and forth continues once a winner is picked.  Perhaps
enlist the help of one of the neutral knowledgeable people in the group
to bring the two groups of authors together in a base draft that
discusses the issues in language both groups can live with with a strict
focus on problems and their explanation.  I may be misreading the 2 IDs,
but I do not think there should be that many sticking points once there
is a decision to work it out.

I think trying to pick a winner from these two documents, both useful
expositions of the issues, is not the best way to produce a problem

Some individual comments on the drafts.

I would recommend also including something like "ignorance of there
being procedures, or lack of knowledge that the IETF & ICANN have
processes"as one of the bullets.

I am not sure how this differentiates from other IETF processes.  They
all take longer than one would expect and always have an uncertain
outcome.   This makes it seem like this problem is somehow special in
that respect.

probably worth indicating that one DNS mechanism that exists is broken
and that others are offering non standard methods of adding metadata or
treating existing data as metadata.

This would seem contingent on there being no way to differentiate

I think the issue here is the breadth of the definition for 'technical
use'. Most any names issue can be defined in such a way so as to have a
technical use.

This section seems to be arguing a case as much as explaining an issue.

Need to also look at the precedent this has set and whether the IETF
wishes to reinforce this as a precedent.

This study is from before the new gTLD program.  The assumption in the
report need to be tested against what actually happened in the round of
new gTLDs before it can be included as part of the fact basis for this
work.  We also need information on the degree of success that the
various mitigation strategies had in overcoming possible problems to
have a full picture of the problem as it has been shown in practice.

This seems an example of a statement that includes both a problem and a
possible solution.

Additionally I think that putting the names pictures in the broader
context is important, even though dnsop WG will be restricted to
solutions based on DNS. Seems important to understand the larger system
DNS is part of these days and moving into the future.
