title: Reading JSONP with Dojo Dojo.io.script
body: <p>I would like to use DOJO to access JSONP data returning from the following url:</p>
  
  <p><a href="http://api.metro.net/agencies/lametro/routes/704/vehicles/callback=recover" rel="nofollow">http://api.metro.net/agencies/lametro/routes/704/vehicles/callback=recover</a></p>
  
  <p>Here is my simple dojo.io.script.get function:</p>
  
  <pre><code>dojo.io.script.get({
  url: "http://api.metro.net/agencies/lametro/routes/704/vehicles/",
  content: {callback: "recover"},
  callbackParamName: "callback",
  load: function(data){
      console.log('OK', data);
  },
  error: function(error){
      console.log('Error', error);
  });  
  </code></pre>
  
  <p>I am getting a "SyntaxError: invalid label"; apparently the server is sending JSON instead of JSONP. </p>
  
  <p>What is the correct format of dojo.io.script.get in this case?</p>
