The W3C Timed Text Working Group has recently published a First Public
Working Draft of the TTML Text and Image Profiles for Internet Media
Subtitles and Captions 1.1, known as IMSC 1.1 [1].

This specification improves on IMSC 1.0.1 [2] by adding support for
essential contemporary practices introduced in TTML2, while retaining
the scope of IMSC 1.0.1 and compatibility with IMSC 1.0.1 documents.

For example, improved support for the following practices is provided:
- Japanese subtitles
- high-dynamic range presentations
- stereoscopic presentations
The TTWG invites you to submit comments at public-tt@w3.org with [imsc1.1]
at the start of your email's subject.
These comments will help shape the development of IMSC1.1. If
substantive changes are requested, you are encouraged to submit use
cases and requirements. The TTWG maintains a requirements document at

TTWG looks forward to working with you on IMSC 1.1.
