Hi all,

I just came across this discussion from ealier and wanted to send it
as a reminder for the WG - when we discuss topic 3 on Monday morning,
we should discuss a change to
http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#naming-track
where multiple tracks can be specified and the separator should
probably be ";" (which is what Davy's implementation already uses, see
below).

Cheers,
Silvia.
