4.3 Clarification to RFC 1123
     http://www.ietf.org/proceedings/08jul/slides/dnsext-3.pdf

TLD labels are always alphabetic per RFC 1123. That needs to
be updated. One reason is the use of internationalized domain
names in top level domains.

Matt Larson & Lars-Johan Liman have volunteered to draft text.

Warnings were conveyed that there are issues both in the
protocol specification and in registration procedures (which
really belong with the IANA). It was also noted that old
implementation may have problems accommodating TLDs that don't
follow the old spec.

Alfred Hoenes noted that there is also a problem with
formal specifications of DNS labels, which often differ from
document to document.

AS noted that the update cannot be an errata, since the issue
came up due to an errata! :-)

[AC 72.9] Matt Larson and Lars-Johan Liman to draft and post new document.
