ISSUE-2324 (captioning): media elements in SVG need ability to associate captions and description [SVG 2.0] http://www.w3.org/Graphics/SVG/WG/track/issues/2324 Raised by: Chris Lilley On product: SVG 2.0 >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.
