Agreed. The idea is to include such language. The client must check the 
Content-Type header to see what the body of the response is independent of 
other issues anyway and we do make that clear. 

On the topic of Accept headers, I tried using that in the past but it is hard 
t make it work in practice. Some clients just have Accept: */* while others 
specify the different types with weights and such... it's kind of a mess I'd 
rather avoid in DALI :-)
