title: In jQuery's ajax success callback, will textStatus ever not be "success"?
body: <p>In the <a href="http://api.jquery.com/jQuery.ajax/" rel="noreferrer">documentation</a> there is a list of possible values that textStatus might be if the <code>error()</code> callback fires ("timeout", "error", "notmodified" and "parsererror") but nothing specified for the <code>success()</code> event.</p>
  
  <p>Are there any other values besides "success" that could be passed to the <code>success()</code> callback? Is this documented anywhere?</p>
