Sorry, forgot to answer the questions regarding what the patch does.

We already have code to expose longdesc to AT software. What the patch
does is that it detects that if an image doesn't have a longdesc
attribute, but does have a aria-describedby which points to a <a> or
<area> element with a href attribute, it exposes the link in that
<a>/<area> as being the location of the long description of the image.
