[ogg-dev] video chapters and subtitles in ogg containers

I'm trying to create files that contain a video stream, one or more
audio streams, subtitles, and DVD-like chapter information.

ATM, I use ogm containers that can handle all this. But although ogm
is supported e.g. by xine (including chapters), it seems to be an
unofficial hack. Is that correct?

I'd like to move to ogg containers, since ogm doesn't support theora
videos. My final goal is one file containing theora video streams,
vorbis audio streams, chapters, and subtitles

Looking into the ogg docs, I found capabilities to handle multiple video
and audio streams in ogg skeleton. But what about meta-data like subtitles
(in text format, of course) or chapters? I couldn't find anything about this.

Question: Is this planned for the future?

Question: Or is it possible and I just didn't see it?

If yes, how could I help (I'm a programmer) ?
