TTML2, provides a standardized representation of a particular subset of textual information with which stylistic, layout, and timing semantics are associated by an author or an authoring system for the purpose of interchange and processing.
In addition to being used for interchange among legacy distribution content formats, TTML Content may be used directly as a distribution format, providing, for example, a standard content format to reference from a element in an HTML5 document, or a or media element in a [SMIL 3.0] document.
The TTML2 specification updates the TTML1 specification by adding vocabulary and semantics to address more of its core requirements, including the addition of support for:
raster images (both foreground and background)
author supplied fonts
audio descriptions and text to speech
ruby text annotations
improved vertical line layout
text emphasis, kerning, letter spacing, shadows, and variants
inline block layout
stereoscopic presentation (for 3-D viewing)
high definition resolution (HDR) presentation
continuous animation
hyperlinks
conditional element semantics
improved metadata extensibility
formalized intermediate document syntax
various other improvements and bug fixes
