CfC: Request transition of TTML1 3ED to CR2

Thank you for this Pierre,

This allows me to issue this Call for Consensus for requesting transition of TTML1 3rd Edition to CR2, noting that publication timetables mean that the deadline for comments of 23rd August will have to move later.

As agreed<https://www.w3.org/2018/07/12-tt-minutes.html#resolution01> during last week's call please review the draft of TTML1 3rd Edition CR2 at https://rawgit.com/w3c/ttml1/feature/move-to-CR2-build/index.html with a view to agreeing to request transition to CR2. Comments can be made on pull request #357<https://github.com/w3c/ttml1/pull/357> or raised as new issues on the repository.

The review period for this Call for Consensus, according to our Decision Policy, ends at the end of 31st July 2018 (UK time).

This version incorporates the following substantive changes:

Merged #355 Update tts:lineHeight='normal' algorithm to match TTML2<https://github.com/w3c/ttml1/pull/355>
Merged #356 Clarify the default value of blur radius for tts:textOutline<https://github.com/w3c/ttml1/pull/356>

Those changes are both straight back-ports from changes already agreed for TTML2 CR2. When we request transition it is my intention to point to the existing TTML2 CR2 exclusion period and argue that these changes are already covered by the exclusion period for TTML2, and that we therefore do not need an additional exclusion period. Both the changes and their context of use are effectively the same. If I am successful in arguing this case, it should allow us to match our intention to reference TTML1 3rd Edition from TTML2, by the time we get to Rec.

Regardless of this, we should request this transition (to TTML1 3rd Ed CR2) if we have consensus so to do.

Kind regards,

Nigel
