Discussion on Caption Model

Hi all,

I've put together a wiki page that I hope will eventually capture all
our different understandings of caption and subtitle rendering
approaches.

I've called the document the "caption model - an abstract model of captions":

              http://www.w3.org/community/texttracks/wiki/Caption_Model

In it I've tried to capture the rendering approaches as I've
understood them from US caption specifications and generalised to
other languages, in particular to vertical rendering.

I may have missed some features of international caption models, so
please have a thorough read and see if you're missing anything.
Also, I may not have got everything right - in particular I wonder if
vertically rendered captions actually ever bottom align - does anyone
know?

Note that one particular purpose of this document is to identify the
requirements for captions and subtitles in WebVTT, so we can see which
features have to be added to WebVTT or generalized.

Please send any criticism to this list for discussion.

Cheers,
Silvia.
