Steve, Richard, I don't know if you have noticed, but publication has already been requested for this draft.
I don't regard this issue as critical enough to delay publication. Of course, If the routing AD has comments he wishes to have addressed before he pushes the draft into IETF Last Call, there would be an opportunity to address it as needed then. Otherwise, it can be addressed as needed as part of IETF Last Call. Obviously, this issue must exist in any RFC that provides an example of base64 encoded material, due to the RFC line length limit. I've looked at some of the (many!) other RFCs that refer to rfc4648. Some say nothing about the fact that line breaks are present in the example, some add a brief phrase about the RFC publication limits, something like Steve's suggestion. We can temper the need with knowing that history. --Sandy, speaking as wg co-chair On May 28, 2015, at 5:34 PM, Stephen Kent <[email protected]> wrote: > Richard, > > Sorry to be late replying to your message, but I just returned from a > vacation trip. > > I think we can do one of two things to address the problem you correctly > identified: > 1- either say that the example in the doc has been formatted for > the RFC, and that no LFs are permitted > 2- adopt your text to explicitly override the "no NL" rule in 4648. > > Steve > >> Hi Geoff, Sam, George, and Steve, >> >> I spotted a bug in this draft: Section 2.1 refers to Base64 encoding, >> defined in RFC4648 Section 4.
