Is this really true? I agree it would be nice, but is there any metadata 
format widely used that offers such a granularity ? From my experience, 
metadata are generally global to a media file and therefore apply to all 
tracks. Complex metadata formats such as MPEG-7 allow to decompose a 
media into pieces (e.g. tracks) in order to attach metadata to these 
pieces, but people tend to say it is too complex.

One more use case for the UC & Requirement document ?
