Hi:

I am an assigned INT directorate reviewer for
draft-ietf-dnssd-mdns-dns-interop. These comments were written primarily for
the benefit of the Internet Area Directors. Document editors and shepherd(s)
should treat these comments just like they would treat comments from any other
IETF contributors and resolve them along with any other Last Call comments that
have been received. For more details on the INT Directorate, see
http://www.ietf.org/iesg/directorate.html.

First, to answer the questions in the review request:

        Internet area: focus on impacts related to internet technologies

        IoT Directorate: Look for and highlight any issues that might be raised
        for IoT devices in this interop,

        Ops: Are there any DNS operational implications to Label interop that
        should be raised.

This does have a potential future impact on how systems resolve names or what
(encoding for) names might be "usable" in the future. But as this document is
about the requirements for future development, this is more informational as to
what the issues are and how they might be addressed. This does mean: - DNS
components that restrict the character set allowed in the "host" label may have
issues coping with DNS-SD. - Device (IoT and otherwise) that use DNS-SD may
need to consider the names used carefully to better interoperate with all
DNS-SD resolution mechanisms.

Second, I believe this document is ready.

This document is Informational and only presents some requirements for future
development. It is well written and fairly clear. While it presents some
options as to how DNS-SD resolves might do to handle resolving names given the
different "character set" uses related to mDNS, DNS, and perhaps other name
resolution systems, it does not specify any particular solution this the issues.

I do wonder if the last sentence in the abstract should be tweaked a bit.
Perhaps changing "outline of the requirements" to "outline of the requirements
for future development" (based on text in the Security Considerations)? Just
saying "requirements" here could leave one thinking that this specifies the
processing (especially given the title, which does not make it clear that this
is a "requirements" document). The other possibility would be to tweak the
title (Requirements on Interoperation of Labels ...)?

Nits (these are very minor and would likely be handled by RFC editor):

- Rigour uses British English spelling.
- "along side" should likely be "alongside".
- Uses "this document" and "this memo", perhaps useful to pick one? RFC
template intermixes usage of memo and document so perhaps this is a non-issue.
