title: AJAX response: sugestions for JSON format?
body: <p>Say I submit a form via Ajax and need a response from the server:</p>
  
  <ul>
  <li>Pass/fail indicator</li>
  <li>On fail, a list of validation errors with associated field ids/names, etc</li>
  </ul>
  
  <p>Is there a standard or best practice for the JSON format for such a structure? If so, I'd like to try to stick to it instead of coming up with my own convention.</p>
