Which suggest that we need working code that addresses a real life
problem. I would certainly agree with that.
But I don't think that in order to produce a working code that
addresses a real life problem it is necessary to have a requirements
document produced by the IETF WG. In fact, I have an existence
proof that plenty of working code that addresses real life problems
have been produced with no requirements documents produced by the
IETF WGs (just think of OSPF, BGP, etc...)
