Please consider expanding the explanation of a null alt attribute (alt=""),as
there has been some confusion:
http://lists.w3.org/Archives/Public/public-html/2010May/0116.html

The draft currently says:

"Purely decorative images MUST be marked up so they can be ignored by assistive
technology with a null alt attribute (alt="") or preferably use CSS techniques.
If the image isn't providing the user any informative content or enhancing
greater understanding of the content, then the alt attribute MUST be empty."

Please consider adding to that section by saying something about how a null alt
attribute (alt="") is removed from the accessibility tree for AT users and the
affects on users who have images turned off.

Also please consider adding something about that it is inappropriate to use a
null alt attribute (alt="") when images have meaning as you explained in:
http://lists.w3.org/Archives/Public/public-html/2010May/0125.html

Thanks.
