The content of the cue.Signature:
- The content is an intermediate TTML document’s body element. This is a view of a TTML document where all nodes in the document are active during the cue’s startTime and endTime. As a result, all begin, dur and end properties have been removed. TTML Styles, Regions and Metadata are stored in cue.styles, cue.regions, cue.metadata respectively. Combining those properties with the given content should suffice to render a TTML cue.
