The HTML-A11Y-TF appears to have suggested to the HTMLWG that longdesc
"DOES provide effective and consistent support for users regardless of
browser and AT":

http://lists.w3.org/Archives/Public/public-html/2011Jun/0204.html

So it's certainly news to some. The HTML-A11Y-TF should send a
clarification to the HTMLWG explaining how poor support for longdesc
actually is.

Bear in mind some people in this TF also understand what really
happens in the world:

I don't think that's entirely accurate. AAP's commentary "is more
concerned that there be a solution with a good user
experience/developer experience and much less concerned with what the
exact code is." A normal link on the image, optionally enhanced with
rel=longdesc where required, is a far better solution to AAP's
requirements at the current time and for the foreseeable future.

Note AAP also appears to be operating under the mistaken impression
longdesc "works with assistive technology today" and "works well for
users today". It seems like a lot of people have been woefully misled
by the incorrect UA/AT support information in H45.
