I hope you also realize that it was pointed out that OIF has assumed 
the assigned value of 3 (probably because IANA had assigned it and 
published it on the iana web pages... Adrian has asked the question
if it is indeed so or not). So if IANA changes it, it may be perceived
by outside world as a weakness. Not sure it is.. but we should check
(or so I think... IANA pls let us know what you think about this).
