There has been a lot of tool development necessary around CMML and Skeleton
in recent years, which is why CMML hasn't progressed much. Now, we are
re-designing some of CMML to address other issues that have come up. If KATE
brings out further requirements for text tracks inside Ogg, it may be easier
to include these findings into CMML to make it richer and extend those
implementations rather than have to go down that whole path again. And...
lots of elements in CMML are optional (as are the URLs for example), so if
you just want to use it for karaoke, you might be looking at a timed text
file and a CSS specification that brings out the timed colouring of the text
etc. This is the preferred way of looking at it from a CMML perspective.

Just my 2c...

Cheers,
Silvia.
