Sorry, but you're only kidding yourself if you think you can even compare an RFC with an ISO publication. There's rigor, formality, lawyers, technical writers, and many others involved. RFC is exactly what it sounds like and what was originally intended for: "Request For Comments". There's no conference or central body (at least to the degree that there is for ISO) and it's mostly done in an ad-hoc manner. Nothing against IETF or RFCs, but you're really comparing apples and oranges. I've been coauthor on two RFCs and it is nothing like an ISO committee.
