I  sent a question to the tls working group about two issues:

1) labeling of identities

2) internationalization of identities.

Hearing nothing. I reminded the TLS working group chair that this
issue needed to be discussed.  I have still heard nothing so I'm
holding a discuss until some actual discussion happens.

[Ballot comment]
Glad to see this, it has been needed.  It might be useful to state that examples of identities form
a very partial list and that URIs and user@... (anything that can be expressed as a UTF-8 string),
can be an identity.  The requirements for inputting the identity allow many applications to use
this.  An RFC Editor note could easily add this, if you feel the clarification would help.

[Ballot discuss]
I think the following comments that I received from the ops directorate should be addressed:

The document says in Section 5:

"To improve interoperability, this
document places requirements on how the identity is encoded in the
protocol, and what kinds of identities and keys implementations have
to support."

However, the draft doesn't actually do this; there are no requirements on
what kinds of identities need to be supported.  For example, Section 5.1
talks about encoding in UTF-8, but doesn't mandate support for any
identity types.  Userid (e.g. user@realm) isn't even included in the list
of identity examples.  Section 5.3 talks about the minimum size of
keys and identities that need to be supported. That's about it.

Section 7.3:

"It should be noted that this is no worse than client certificates, since
they are also sent in cleartext."

Actually, certificates don't have to be sent in cleartext in TLS; it is
possible to establish the TLS channel via server authentication only, then
reauthenticate with the server requesting a client certificate.

[Ballot comment]
sect 5.1 has as first bullet:

  o  IPv4 addresses are sent as dotted-decimal strings (e.g.,
      "192.0.1.2"), not as 32-bit integers in network byte order.

Probably better to adhere to RFC3330 and use 192.0.2.1 or some
other address in the 192.0.2.0/24 range.

IANA Comments:
Ack Ted's comments.
Are the authors sure that they do not want to have this registry published on the IANA website?  If so, a line or 2 about registration rules would need to be added.  If not, the IANA would just like to confirm that there are NO IANA Actions.

The document says:

  there are no IANA actions associated with this document.

Note that IANA does have a TLS-related compression registry:

http://www.iana.org/assignments/comp-meth-ids

I also kind of think that a registry TLS ciphersuites wouldn't
be a bad idea; not a job for this document, obviously, but
it does seem useful.
