Subject: Re: [ietf-dkim] Output summary - proposing ODID "Originating Domain
Identity"
The advice that a verifier can ignore the "l=" tag was in RFC4871, so
copying it to RFC4871bis doesn't seem like a problem to me.
You can't ignore the *tag*. That's the normative change. Whether you
ignore the *output* is another matter. But of course you can't ignore
the output because l= is "internal". Yet another problem.
So the issue is that someone might read it as "leave l=<value> out of what you
feed to the hash" versus "hash it, but ignore what it's telling you"?
If so, I agree, we should fix that.
