Hi Ian,

I like how your message cuts to the point.

If I may, I would like to replace "is important" with "CONVEYS 
INFORMATION", as in:

(1) Image DOES NOT CONVEY INFORMATION, alternative text is available. 
(alt="")
(2) Image CONVEYS INFORMATION, alternative text is available. (alt="...")

Now, in my opinion, a missing "alt" attribute actually represents:

(3-REWORDED) Image MAY OR MAY NOT CONVEY INFORMATION and alternative 
text is not available.

Now, I think there is a fourth state that I see use in representing:

(4-NEW) A tool (CMS, etc.) knows that the image CONVEYS INFORMATION 
(e.g. someone uploaded it from their camera, so it's probably not a 
blank placeholder), but alternative text is not available.

That said, I'm not sure how (4) should be represented (e.g., some have 
suggested something like alt="_none").

Cheers,
Jan
