Something more complex is exactly what I don't want :) Of course I could
accomplish that by not using any additional tags. However, for a simple
text stream format as I want, even if I don't use any of the fancy
features of annodex, it would still depend on libexim for XML-parsing
and libcmml for parsing the... well CMML. Of course since you've already
made annodex that wouldn't be my problem, I'm just saying that annodex
doesn't seem like just a subtitle format. Which of course it isn't

Yes, I've now read the full spec for annodex, and I must say it seems
very cool. Linking into multimedia files and from within media files to
the outside world is something that may prove very useful.
Nevertheless, I feel that there is too much "feature overhead" in
annodex for what I'm thinking. There's really no reason why both annodex
and the simple subtitle format I envision could exist, since they are

BTW, I followed your advise and tried to install the tools. However,
libannodex would not build, failing on libcmml. I could provide some
more detailed information if you mail me privately, because theora-dev
isn't annodex-dev. Instead I tried reading the man pages, but they
were... how to say... sparse on information.
