CMML: http://www.annodex.net/specifications.html#cmml

which provides XHTML-like <meta> tags, as well as freetext descriptions
and <a href=""> anchors. These are contained in timestamped <clip>
elements, and packets of that XML are stored in a separate track in Ogg.

Ogg has the nice property that it's possible to rip out and re-edit
individual tracks, so you can add timed metadata even if you don't know
the details of what the other tracks are.

cheers,

Conrad.
