Hi Jonas,

That would be great. I need all of the help I can get :-) But it would
be best to try to come to agreement on any substantive changes first.

Yes, I see your point. The new "guidance for conformance checkers"
language makes that section moot. I agree slicing the title section
would simplify things. I removed both the title section and the email
sections for simplicity sake. They are both  listed in the impact
section and Issue 80 specifically covers title anyway.

We may need to think about that a bit more. The key point  is that alt
is not fallback. Alt is equal to src.

But maybe we can simplify choices, if people can agree to mandatory
alt with no exclusions, maybe the definition could be pulled from this
change proposal into its own change proposal. And we can work on it
there.

Can anyone not live with mandatory alt and no exclusions?:

We would be replace the current guidance for conformance checkers text:
http://www.w3.org/html/wg/wiki/ChangeProposals/ImgElement20100504#Replace_the_Current_Guidance_for_Conformance_Checkers_Text:

With suggested guidance for conformance checkers text:
http://www.w3.org/html/wg/wiki/ChangeProposals/ImgElement20100504#With_Suggested_Guidance_for_Conformance_Checkers_Text:

Thoughts?

Best Regards,
Laura
