Correcting something I wrote (thanks to Rob Elz):

According to RFC 4282 it should be possible for an NAI realm to begin

RFC 3315 refers to, which this document references. As a matter of
correctness, I might simply reference RFC 4282 instead of RFC 3315.
There is confusion here. 1035 has display guidelines relating to the
use of numbers. RFC 4282 indicates makes the claim that the limitation
is stronger. RFC 2181 clarifies this in Section 11. Either reference,
therefore, would work, and the authors should ignore the above quoted
text. In time it may be worth RFC3315bis referencing 1035 and 2181, and
RFC 4282 doing the same.
