What was said is "SHOULD = OPTION", but RFC2119 says "OPTIONAL" is the same as "MAY". That's the contradiction. > The only difference between "SHOULD" and "MAY" is that the implementor / > deployer needs a good excuse to not implement / employ a "SHOULD." > That's not the same as "IGNORE". But that's a big difference. I think some people are being cavalier about the "good excuse" part, and that's where I have a problem. RFC2119 is not unclear on this point. _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
