I interpret this answer as a +1 for Philip case. Feel free to tell me if 
I'm wrong. My reasoning:
   - http://www.example.com/football.movie#xywh=10,20,30,40&action=track 
is NOT a valid media fragment according to our ABNF syntax. Nothing is 
sent to the server in case of a spatial fragment so let's take another 
   - http://www.example.com/football.movie#t=10,20&action=track is NOT a 
valid media fragment according to our ABNF syntax. So there will no 
Range request issued. The UA will simply get the whole resource ... and 
I understand this is not what you would like to happen.
