media descriptions in HTML

this is ACTION-329

Does HTML provide mechanisms to describe the various media it can introduce? I *think* it does except for transcripts and alternatives for video posters:

img - alt, longdesc
canvas - content inside it
video - track elements, but missing something for a poster, and linking of transcripts
audio - track
SVG: make it accessible directly... still work to be done there but that is why there is an SVG task force
figure / figcaption
CSS background images - No! Don't go there!

anything I missed?

cheers
