Hi Mat and Adrian, Good discussion.

I doubt that will happen in all (or most) cases, sadly, so I agree that simplicity is important. However, making this a requirement for validation puts the onus on the developer and acts as a reminder to do his/her job. >> >> Outside of human authors I see this is a simpler issue for WYSIWYG applications and generated HTML to handle -- just duplicate the @alt text that has been provided elsewhere (again, presuming the user has even provided it).. Getting toolmakers to do that, however, I know from experience is an uphill battle, but is at least possible. Agreed. >> I think the spec authors don't have such an absolute view. I feel they chose the option most likely to be supported with the least confusion and pre-existing use cases. Authors can still decide to exclude it, they'll just be going against the spec. > > Speaking at least for myself, this is the case. It may be a bit redundant to specify the `alt` attribute twice, but it seems to me that this is the path of least resistance in terms of authorship—leading to a better overall experience for users on assistive technologies. Agreed. >> It (aria-labelledby) is a bit more complicated. It also feels more complicated than the replicated @alt, which doesn't mean you can't use ARIA. It is complex and vendors have raised concerns. http://rebuildingtheweb.com/en/aria-for-content-doomed/ > I agree. Now, likewise, I see no reason why `aria-labelledby` couldn’t be used here, but I’m not convinced we should make it a requirement. aria-labelledby does not make the image element valid. The Chairs decision found "to be redundant with other constructs". http://lists.w3.org/Archives/Public/public-html/2011Apr/0451.html IMHO I'd stick with alt. Best Regards, Laura -- Laura L. Carlson
