Philip's example only works if there is an on-screen longer textual description
of the media asset, and does not address the use-case of when there is no text
on-screen. <video> and <audio>, like images, require a means to ensure that a
longer textual description can be provided regardless of visual design
considerations. The longer textual description is not to be confused with a
transcript

Related to Issue 30 - Should HTML 5 include a longdesc attribute for images

Possibly related to Issue 142 - No alternative text description for video key
frame (poster)
