Use of LWSP in ABNF -- consensus call

2007-05-14 12:10:57

The IESG reviewed <http://www.ietf.org/internet-drafts/draft-crocker- rfc4234bis-00.txt> for publication as Internet Standard and would like to know if there is consensus to recommend against the use of LWSP in future specifications, as it has caused problems recently in DKIM and could cause problems in other places.

Some discussion on this point already:
 - http://www1.ietf.org/mail-archive/web/ietf/current/msg46048.html
 - http://www1.ietf.org/mail-archive/web/discuss/current/msg00463.html
 - http://mipassoc.org/pipermail/ietf-dkim/2007q1/007295.html
- https://datatracker.ietf.org/public/pidtracker.cgi? command=view_comment&id=66440 (in this tracker comment, Chris Newman recommended to remove LWSP, but for backward-compatibility it's probably better to keep it and recommend against use)

Thanks for your input,
Lisa Dusseault
