[I use "@alt text keywords", as term for both the curly brackets and the role="photo tagged"/@tagged proposal.] I don't agree that the @alt text keyword proposal "is for meta data", if by that you have @role in mind. (See my reply to Rob [1].) Rather, for users, it offers a way to discern an @alt with a textual equivalent from an @alt with merely some general tags. For authors, it offers a method of what we could all "lesser degree of @alt text conformance". Hence, of course, whether it does actually conform, is an important question. We did, however, discuss the possibility of having a "minimum alt text" in keyword form a few times. Bear in mind that we discuss - I think - photo albums and that kind of stuff. It seems that WCAG is far more occupied with non-text content with a "meaning" or with a technical functionality - e.g see Technique G82 [2] and H37 [3] - than it is with photo albums. As an example of what in WCAG 2.0 such @alt text keywords *perhaps* could break, I have looked at F30. [4] F30 mentions "placeholder text", "programming refererences" (of the kind "picture 1", "picture 2") as non successful @alt text. I would say, however, that saying "photo" is one step up from e.g. "picture 1". On a photo web site, 'photo' as a keyword would be useful if it was restricted to photos, and not used on other graphics. We talk about conscious tagging, and not accidental programming output. Hence, I don't think it comes in the F30 cathegory. (I am not certain were to draw the line, though, between such keywords and "regular" alt text in abbreviated/keyword form.)
