Maybe it should be added?

> Besides, the current media type for EXI is application/exi. Thus it would make perfect sense to have +exi entries. Furthermore, EXI is totally different than gzip, which is a generic encoding that can be applied to anything. EXI can be applied only to XML objects, and in particular EXI is often used in a schema mode where it is only applicable to a single schema. Thus the form application/schema+exi makes even more sense, as that EXI format is actually specific to that particular schema and the media type tells you everything that is needed to decode the representation. 

These arguments were part of the discussion during EXI, and W3C decided to use a content-coding.
