The following errata report has been verified for RFC5536, "Netnews Article Format". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata/eid5116 -------------------------------------- Status: Verified Type: Technical Reported by: Paul Kyzivat <pkyzivat@alum.mit.edu> Date Reported: 2017-09-14 Verified by: Alexey Melnikov (IESG) Section: 3 Original Text ------------- fields =/ *( approved / archive / control / distribution / expires / followup-to / injection-date / injection-info / lines / newsgroups / organization / path / summary / supersedes / user-agent / xref ) Corrected Text -------------- optional-field = <see RFC 5322 Section 3.6.8> news-fields = approved / archive / control / distribution / expires / followup-to / injection-date / injection-info / lines / newsgroups / organization / path / summary / supersedes / user-agent / xref optional-field =/ news-fields Notes ----- In Section 3 of RFC5536, the ABNF syntax provided does not do what is clearly intended. What is specified is: fields =/ *( approved / archive / control / distribution / expires / followup-to / injection-date / injection-info / lines / newsgroups / organization / path / summary / supersedes / user-agent / xref ) and that extends RFC5322: fields = *(trace *optional-field / *(resent-date / resent-from / resent-sender / resent-to / resent-cc / resent-bcc / resent-msg-id)) *(orig-date / from / sender / reply-to / to / cc / bcc / message-id / in-reply-to / references / subject / comments / keywords / optional-field) message = (fields / obs-fields) [CRLF body] The problem is with the way things are grouped. Let me give a simpler example: foo = *("a" / "b") / *("c" / "d") This means the following are valid: ab aabb bab cd ccdd dcd But the following are not: abcd ac I think it is clear that the latter is intended to be valid, for which the syntax would be: foo = *("a" / "b" / "c" / "d") The above fix is based on discussion with Pete Resnick (editor of RFC 5322), Julien ÉLIE, Alexey Melnikov and Paul Kyzivat. -------------------------------------- RFC5536 (draft-ietf-usefor-usefor-12) -------------------------------------- Title : Netnews Article Format Publication Date : November 2009 Author(s) : K.
