I think this goes to far, as it explains the interaction between 
Content-Encoding and Content-Type.

That makes sense.

Related issue: Section 5.5 currently is phrased as if Content-Encoding 
only works in presence of Content-Type:

"The entity-header field "Content-Encoding" is used as a modifier to the 
media-type. When present, its value indicates what additional content 
codings have been applied to the entity-body, and thus what decoding 
mechanisms must be applied in order to obtain the media-type referenced 
by the Content-Type header field."

It seems to me we should rephrase that as well.

BR, Julian
