title: Web API Return OAuth Token as XML
body: <p>Using the default Visual Studio 2013 Web API project template with individual user accounts, and posting to the /token endpoint with an Accept header of application/xml, the server still returns the response in JSON:</p>
  
  <pre><code>{"access_token":"...","token_type":"bearer","expires_in":1209599}
  </code></pre>
  
  <p>Is there a way to get the token back as XML?</p>
