Right. I am happy for the group to consider them, and provide feedback
as the case may be. I do not think it is however reasonable to
necessarily hold-off and/or require significant changes to IMSC 1
and/or TTML 2 (as they approach LC) based on a WD. There is always the
opportunity to address the final published requirements in future
revisions of the specifications.

Best,
