Re: Obsoleting XML 1.1

Thanks for highlighting this Pierre.

Looking at this from a TTWG perspective and reviewing the comments, it seems that:

  1.  If XML 1.1 really is obsolete and we don’t need it because XML 1.0 5th Edition does everything that anyone does, then W3C should be motivated to direct people away from it.
  2.  TTML1 3rd Ed and TTML2 only reference XML 1.1 for production 4a which is now available in the identical form in XML 1.0 5th Edition, so they could be modified without harm to reference XML 1.0 instead.
  3.  IMSC 1.1 references XML 1.0 and does not reference XML 1.1.

From a group perspective therefore I would propose:

A) we should remove the references to XML 1.1 in favour of XML 1.0 5th Edition, regardless.
B) if there is a TAG determination that XML 1.1 is genuinely obsolete then we request coordination with the team so that they do not obsolete XML 1.1 before we have updated TTML as per A above.

Thoughts?

Kind regards,

Nigel

Actually, it is normatively referenced by all TTML RECs going back to TTML1 1st Edition. See my comment at [1].
