>>> Dear Accessible Platform Architectures (APA) Working Group,

>>> TTML2, provides a standardized representation of a particular subset of
>>> textual information with which stylistic, layout, and timing semantics

>>> In addition to being used for interchange among legacy distribution

>>> 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
>>> The TTWG invites you to review this draft, and requests comments to be
