Hi, David. One note on your review: > idnits didn't like the reference to RFC 20 for ASCII: > > ** Downref: Normative reference to an Unknown state RFC: RFC 20 > > RFC 5234 (ABNF) uses this, which looks like a better reference: > > [US-ASCII] American National Standards Institute, "Coded Character > Set -- 7-bit American Standard Code for Information > Interchange", ANSI X3.4, 1986. Except that (1) many IETF documents do use RFC 20 and (2) the RFC 20 reference is not for ASCII: it's for RS, the Record Separator character, which is explained in RFC 20, Section 5.2. Barry
