Hi Brian/ Jari,
I see a few more inconsistencies regarding the same RFC:
Since ESP encryption and authentication are both optional, support
for the NULL encryption algorithm [RFC-2410] and the NULL
authentication algorithm [RFC-2406] MUST be provided to maintain
consistency with the way these services are negotiated.
>From RFC4301
- confidentiality-only (MAY be supported)
- integrity only (MUST be supported)
- confidentiality and integrity (MUST be supported)
I think only encryption is now optional in RFC4301. We do not
necessarily need to allow NULL authentication either. Actually this is
still a problem with RFC4305 and it was not updated because the issue
was found late in the RFC process.
Thanks,
Vishwas

IMHO, the reference updates should be done during AUTH48 without
further discussion, but making AH optional seems like a substantive
change.
Personally, I would support that change, i.e. s/MUST/MAY/.
