  The RADEXT WG is in the last stages of publishing the updated NAI
document:

https://tools.ietf.org/html/draft-ietf-radext-nai-10

  This defines a standard for "username@realm" handling, where "realm"
is a fully qualified hostname.  It would be useful to reference that
from the saslprepbis document.

  The NAI is used for EAP (802.1X), AAA, 3GPP, and international roaming.

  The NAI is a subset of the "userpart" defined in Section 3.1 of the
saslprepbis document, in that it *requires* "username@realm", and the
"realm" part is a fully qualified domain name.

  Hmm... I've just noticed that the ABNF in the NAI allows for IP
addresses in the "realm" portion.  That's not the intent.  I'll have to
go fix that.

  I'd like to be sure that the NAI document is compatible with (or at
least not in violent disagreement with) the precis work.

  Alan DeKok.
