I agree it should not be required.

(Note that even HTML5 allows recipients to reject non-conforming HTML)

Indeed; but there are pressing problems and less pressing problems, IMHO.

Not sure.

We will have to produce a new draft, request publication and go to AD 
review before we get to IETF LC anyway.

What's wrong with processing additional feedback during IETF LC?

I'd encourage you to do it openly on the list, to get constructive feedback from others as you go (thereby increasing your chances of delivering something people will accept). However, if Adam does this, I'd ask people not to question *why* it's being done.

I have my doubts that we will go to IETF LC this year if we do not 
request publication much earlier.

Also, I'm planning to revise RFC 5987 and C-D for publication as Draft 
Standards as soon as possible (the interop research has been done 
already, and sufficient implementations *are* there). Maybe it would 
make sense to address the error handling discussion in that revision.

Thanks.

Merci.

Clarifying: with "this work" I meant doing research and filing bugs 
against the implementations, not the spec :-)
