You also planned several ABNF updates confirmed by the Community. Last
state I know was "not yet ready", that was some months ago.
...and I think these last changes /must/ go in, if at all possible.
Also, the council website URL in section 12.2, "The Received-SPF mail
header", needs to be changed from "http://spf.mehnle.net/"; to "http://www.
openspf.org/Council" (with a capital "C"). (See the attached patch.)
Yes, this is on my TODO list, along with the reference to
spf.pobox.com
I also wonder if the following change, which I hadn't proposed[1] in time
for draft-schlitt-spf-classic-02, could make it into the last edition?
(Patch attached, too.)

I don't see any reason to tell implementations how to do their job.
This may be a good way of doing things, but I see no reason that
should be in the draft. It is already too long.
