Yes, I just re-read that, too, after you pointed it out. I don't like
it, but ok. Then we have to make sure we change it and we discuss what
to do in the HTTP headers etc.

I suggest only allowing multiple track params in the URI and
converting them to a combined value in the HTTP header. This is the
way it is mostly written right now (not completely though), but it
needs to be made more explicit and explained that the UA has to change
it over.

Cheers,
Silvia.
