Summary: insufficient accessibility fallback for <audio> or
<video>
Product: HTML WG
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Spec bugs
AssignedTo: dave.null@w3.org

The new <audio> and <video> elements do not permit fallback content.
This is a regression from the more generic <object> (though not from <embed>).
The reasoning is that authors SHOULD use accessibility aids built into the
underlying media. While this is indeed desirable, it is not always possibe --
and relies on the browser being able to interpret the media stream, at least to
some extent.
An additional fallback step is required for authors who cannot modify the
original stream, and for users of browsers which do not understand the format
well enough to extract accessibility information.
The fallback already available for <object> would be sufficient, as would a
more specialized element such as the sometimes proposed <alt>.
