minutes from yesterday and some fixes

Hi all,

I think great progress was made yesterday. I am very sorry I missed
the afternoon part. I would appreciate if minutes could be posted?

Also, I just made some changes to the spec:

* I introduced the new Content-Range-Equivalent header (which made it
heaps cleaner)

* I introduced multiple track names in a track dimension and removed
stray mention of single quotes

Cheers,
Silvia.
