For users who can use audio but not video, authors should either provide audio descriptions in the video file as alternative tracks, or supplemental material provided in links available to everyone near the video. For users who can use video but not audio, authors should provide subtitles, captions, or transcripts either in the video or audio file as supplemental tracks, or in supplemental materials available to everyone in links near the video. For users who can use neither video nor audio, supplemental materials are likely the best thing for an author to provide, again, in links visible to all. For users of legacy UAs that don't support these features, feature-rich alternatives such as plugins can be provided as fallback content for <video> and <audio>. Captions and subtitles can be included either directly in the media file, or scripts can manually support external resources using the cue range API. Going forward, we will probably also support dedicated formats that UAs can merge with the video to handle showing external subtitles natively. I don't see a need for an alt="" attribute here. What problem would it solve that is not solved by the above solutions? -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
