Just reading the current spec, we actually have only ":" and ","
specified as substructuring elements (see
http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#fragment-structure).

So, this should actually be
#track=audio(audesc,en),video(main,en),text(cc,en),text(sub,fr)

Davy, you may need to change your implementation, or alternatively we
should add the ";" as another substructuring element.

Cheers,
Silvia.
