Unless I've misread the record, all other votes on advancing ABNF from Draft to Full are positive or neutral,. except for your own Discuss. Is this correct? 2. The ABNF is a candidate for moving from Draft to Full. Will removing a rule (that is already in use?) or otherwise changing the semantics of the specification, at this point, still permit the document to advance? I had the impression that moving to Full was based on some serious beliefs about a specification's being quite stable. Making this kind of change, this late in the game, would seem to run counter to that. > as it has caused problems recently in DKIM and could cause problems in > other places. Semantics: "Could cause problems in other places"... The DKIM hiccup was the first one I'd heard about. By contrast, "linear-white-space" was defined in RFC733, in 1977, with RFC822 retaining that definition. It is defined in those places as essentially the same as LWSP in the current ABNF Draft Standard specification. This seems to be one LWSP problem in 30 years. Is this really a sufficient basis for changing the semantics of something that has been stable and widely used for 10-30 years (depending upon how you count)? Are we reasonably comfortable that making the change will not create new and different problems, such as for other uses of ABNF? d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
