Understood. But the *EPub* application will do that no matter what 
format the media type has.

The question was about the case where you do *not* have an EPub reader 
installed. Would a user expect to see the contents of the archive, or a 
notification that the system doesn't have an application for that type. 
I believe the answer is "the latter" for most non-programmers.

Exactly; the question is what generic processing can be done.

For +xml we know about some use cases in UAs, such as XmlHttpRequest. 
For +json, it would be the same.
