I did not mean to protest against the particular KM function. My complaint
was that the KM function should not be `burned in` the spec as there may be
reasons, such as a possible future crypto weakness in the particular KM
construction, for people to prefer another KM function. Furthermore I noted
that the KM function should be part of the AgreementMethod. Indeed RFC 2631
defines a particular key agreement method (Diffie-Hellman of course) and
therefore the fact he defines the KM construction there is exactly in line
with my suggestion.
