Just to add to my position on using aria-describedby and
aria-labelledby in response to Al's original message. I think
aria-describedby could be considered an appropriate alternative to
longdesc when the description exists in the same page, but obviously
not when the description is in another document. I can also see there
may be some edge-cases when aria-labelledby may be considered a
suitable replacement for alt. These are edge-cases, as ARIA was
designed to bridge the accessibility gaps with the current structure
we have. Providing alt text for images wasn't one of those gaps, as
there is already a suitable attribute.

Cheers,


Gez
