4.1.1 Instance Names

 -- Should the document also disallow Unicode Control characters ?


4.1 Structured Instance Names

   The <Instance> portion of the Service Instance Name is a single DNS
   label, containing arbitrary precomposed (Unicode Normalization Form C
   [UAX15]) UTF-8-encoded text [RFC 3629]. It is a user-friendly name.
   It MUST NOT contain ASCII control characters (byte values 0x00 -
   0x1F) but otherwise is allowed to contain any characters, without
   restriction, including spaces, upper case, lower case, punctuation --
   including dots -- accented characters, non-roman text, and anything
   else that may be represented using UTF-8.

How does this interact with draft-ietf-tsvwg-iana-ports? I think it would be worth pointing out here to sections that define more restricted formats.


6.4 Rules for Keys in DNS-SD Key/Value Pairs

   The characters of "Key" MUST be printable US-ASCII values
   (0x20-0x7E), excluding '=' (0x3D).

This needs a reference to US-ASCII.

  This document has quite a list of ID nits that should be fixed before
  publication (outdated references, not using example domains/prefixes,
  etc.)

I do not want to hold up publication of this document, so I am entering this as a comment, but hope the authors
will take the time to review the use of non-example domain names in sections 4.1 and the various subsections of 14.

I am not sure that the use of non-example domains in section 4.1 adds anything that "example.com" wouldn't provide:

  a conventional unicast DNS domain name, such as "ietf.org.",
   "cs.stanford.edu.", or "eng.us.ibm.com."

Since section 14 is a worked example, I expect that no revisions are possible, but the authors should consider the
ramifications of readers playing along at home...

1. The User Interface Considerations might be more appropriate as an appendix.

This document contains several instances of opinion and observation that are not
going to be useful for building interoperable implementations of the protocol.
Earlier versions of draft-cheshire-dnsext-multicast had similar text that was
polished out as it was completed, leaving a better document for implementers.
Please consider a similar editorial pass for this document.
