ISSUE-2: What is the mime type of a media fragment? What is its relation 
with its parent resource?

Raised by: Raphël Troncy

Related to a discussion started by Guillaume [1].

A media fragment URI can be used for addressing, for example, a 
particular audio track of a mkv movie, or a particular key-frame of a 
video. What is the resulting mime type of the secondary resource 
specified by the fragment (audio, thumbnail, text)? Should we specify it 
in the recommendation?
What RFC3986 does say about the mime type of a fragment [2]?

Side issue: in case we create a new resource (i.e. using the query '?' 
parameter instead of the fragment '#' parameter), how do we make 
explicit the relationship with the parent resource it was extracted from?
Do we use Link: rel="part_of" <video_uri> as suggested by Yves [3]?
