Actually, something that just dawned on me: we have to fix aria-describedby no matter whether it is a valid replacement for @longdesc. Since browser APIs all deal with @aria-describedby differently, it's obviously underspecified and for that reason not quite as useful as it could be. Is that being worked on? Should I provide input somewhere? Cheers, Silvia.
