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

First, that is not possible, as we have already discussed it, since for 
updating IANA registries, you need to 'own' the format, which obviously 
we don't. It seems to me insane to try to register the fragment 
semantics for the 100+ multimedia formats, without counting all new ones 
appearing every year ...

Second, it is from my point of view not necessary. XPointer lives 
without for a period of time without problem. I cannot find a registry 
for the SVG fragment? Is someone aware of that?

Third, that was not really the question asked in the ISSUE, although, I 
agree it is not completely clear. The server specifies using http header 
what is the type of the resource is serving. Silvia's suggestion is to 
encode in the URI this type, for example, in the case we extract a 
keyframe from the video. Is it the only way to go?

Best regards.
