"Intermediate nodes MUST use the "utf8-realm" portion of the NAI
   without modification to perform this lookup.  Comparisons between the
   NAI as given in a AAA packet, and as provisioned in a logical AAA
   routing table SHOULD be done as a byte-for-byte equality test."

New text:

"Intermediate nodes MUST use the "utf8-realm" portion of the NAI
   to perform this lookup.  Comparisons between the NAI as given in a
   AAA packet, and as provisioned in a logical AAA routing table SHOULD
   be doneusing a normalization-insensitive comparison function."

Rationale: consistent with what the filesystem community and other parts
of the apps community (especially outside the IETF) are doing.  One
obvious normalization-insensitive comparison function is what you
propose: normalize both sides.  However, the important thing in terms of
implementing this is to be normalization insensitive. We want to
encourage people to call into their unicode library, not roll their own.
