We have further discussed this during today's telecon, but for the 
record: my rationale is that as soon as a Range request is issued, a 206 
Partial Content should be returned. Therefore, the problem amounts to 
whether the UA should issue a Range request at all when it notices the 
fragment will be equal to the entire resource.

I understand the good will of optimizing the communication between the 
UA and the server but I think we should not put too far away the 
intelligence that the UA should have.
