Re: [mail-vet-discuss] tightening the ABNF

I think it would be good to explain the use of the various methods with 
the various ptypes. I just don't agree with it being placed into the 
syntax layer.

Just my two bits; YMMV.

So do you also disagree with explaining and limiting which methods
should use the various ptypes? Neither the syntax or discussion of
semantics gives any guidance at all.

I'd like to suggest that the current ABNF doesn't do a very good job at
limiting silly states, in particular about the relationship of propspecs
to methodspecs. What exactly does dkim=hardfail smtp.mailfrom mean? I'm
pretty sure that it's meaningless, but neither does the ABNF limit this,
nor does the current draft even discuss why you'd choose one of the
ptypes at all.
