Hi,
I am not sure whether I missed this in the discussion, but I can see some
problems with Copyright statements in early drafts. There may well be
people or organizations which already hold patents or copyrights for
things that find their way into I-Ds. If they are not actively involved
in that particular WG, they may not discover any infringements until the
RFC is in IETF wide Last Call. Hopefully we provide for Copyright
objections at that stage, even if there has been umpteen earlier I-Ds on
the subject.
