media elements in SVG need ability to associate captions and description
- State:

- Description:
- From http://www.w3.org/Bugs/Public/show_bug.cgi?id=9697
The <audio> and <video> elements in SVG need to have a peer element to contain
timed text to support captions, subtitles and the text of descriptions. While
an approximation to captions can be done using <animation>, this is not a good
substitute to using a dedicated timed text format and there are no controls for
the user to find them.
Proposal (1)
Allow <foreignObject> to have the Attributes for runtime synchronization so
that for example an external TTML file may be referenced, or an embedded TTML
resource.
Proposal (2)
Add an explicit <timedText> element equivalent to <video> to provide such
references.
Proposal (3)
Add system properties for captions, descriptions and subtitles in order to
control the rendering of these formats. - Related Actions Items:
