New CR draft

Attention TTWG.

As no implementation information has been forthcoming, Philippe and I have edited the CR document to remove the 'at risk' dynamic flow feature. In addition the conversion to the TTML name has been completed. The document is available at [1].

Note, due to some intense discussions on the HTML5 WG list recently, I have also changed some of the language around the styling vocabulary. This now  hopefully makes it clearer that XSL is used as an exemplar technology that exhibits presentation semantics which would render TTML as an author would expect; but that TTML does not require an XSL processor. These changes are editorial in nature, and not substantive, as at no time has it been the intention that TTML require XSL.  However please review these changes in case I changed something significant in error.

One of the benefits of these editorial changes is that it will make it easier to migrate TTML to a CSS3 stylesheet based presentation system, as that standard matures. To that end I have made one technical change, which is to make the content model of the <style> element EMPTY. This allows the option in the future to use that element to contain inline stylesheet data as PCDATA, or to point to an external stylesheet resource without invalidating existing content. I do not consider this a substantive change either, since the content model previously only allowed metadata.

Please review this latest draft carefully. This draft should replace the current CR draft shortly. Absent any objections on the list (i.e. silence will be deemed consent), I intend to convene a TTWG call on the 11th of June to formally move that TTML be advanced to PR.
