Well, we developed CMML 10 years ago and it hasn't really been used
widely. If it works for you for your use case, then feel free to use
it. It's not going away. I've just basically deprecated it from new
support and I suggest going with Kate for Ogg. For the Web, I would
suggest WebVTT, which I expect eventually will go into Ogg through
Kate, and into Matroska through WebM. Just my 2c here though. If CMML
works for you now, go for it!
