title: Should a REST service expose a XSD for XML responses?
body: <p>We've build a REST service that depending on the accept header will return XML or JSON to the client, or depending the content-type header will accept XML or JSON.</p>
  
  <p>Now a recent integrator asked us whether we have a XSD schema for our XML responses and requests.</p>
  
  <p>Is this a common practice to have when developing REST services?</p>
