Request a11y review of IMSC 1.2

Dear APA WG

As per the horizontal review requirements TTWG requests an accessibility review of IMSC 1.2, based on the Editor's Draft at https://w3c.github.io/imsc/imsc1/spec/ttml-ww-profiles.html


The intended progress of this is FPWD -> CR -> PR -> Rec. The changes relative to the IMSC 1.1 Rec at https://www.w3.org/TR/ttml-imsc1.1/ are listed in Appendix L at https://w3c.github.io/imsc/imsc1/spec/ttml-ww-profiles.html#substantive-changes-summary and are intended to meet the requirements captured in https://w3c.github.io/imsc-vnext-reqs/


The TTWG has agreed<https://www.w3.org/2019/10/10-tt-minutes.html#x05> to publish as FPWD and is requesting prior to that publication for expediency. No further feature changes are expected.

We suggest that the single added feature of most interest in this review is the inclusion of a mechanism to reference fonts from external URIs which is closely related to the CSS @font-face rule.

Kind regards,

Nigel Megitt

Chair, TTWG
