Lisa,
That leaves an ambiguity about behavior from which neither SMTP
clients nor domain administrators can figure out what to do. To me,
that ambiguity is the one case that is a showstopper. It also, IMO,
creates a "known technical defect" and that would exclude even
publishing something as Proposed, much less Draft.
Yup, I certainly prefer removing ambiguity, but I do see it as a
realistic fallback to at least document the known ambiguity and lack
of consensus, even for a Draft Standard. I was of course partially in
jest about WWTHD and answering Arnt's direct question about how to
word something, not whether that was the best option.
thanks,
Lisa
