title: What Content-Type should a 204 No Response use?
body: <p>When building a RESTful HTTP service, and a Response is given with a 204 No Content (e.g. after the Consumer issues a DELETE Request), what Content-Type should the Response include?</p>
  
  <p>Should it be omitted?
  Is there a preferred Content-Type?
  Should it be the same Content-Type of a GET Request to the same Resource?
  Does it not matter whatsoever?</p>
