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

The draft currently says:

&quot;Purely decorative images MUST be marked up so they can be ignored by assistive technology with a null alt attribute (alt=&quot;&quot;) or preferably use CSS techniques. If the image isn&apos;t providing the user any informative content or enhancing greater understanding of the content, then the alt attribute MUST be empty.&quot;

Please consider adding to that section by saying something about how a null alt attribute (alt=&quot;&quot;) 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=&quot;&quot;) when images have meaning as you explained in:
http://lists.w3.org/Archives/Public/public-html/2010May/0125.html

Thanks.</thetext>

    <thetext>Bug triage sub-team notes the task force has an interest in this but does not need to prioritize its work on these. Steve and the reporters can follow the usual process on these.</thetext>
