title: Delete multiple records using REST
body: <p>What is the REST-ful way of deleting multiple items?</p>
  
  <p>My use case is that I have a Backbone Collection wherein I need to be able to delete multiple items at once. The options seem to be:</p>
  
  <ol>
  <li>Send a DELETE request for every single record (which seems like a bad idea if there are potentially dozens of items);</li>
  <li>Send a DELETE where the ID's to delete are strung together in the URL (i.e., "/records/1;2;3");</li>
  <li>In a non-REST way, send a custom JSON object containing the ID's marked for deletion.</li>
  </ol>
  
  <p>All options are less than ideal.</p>
  
  <p>This seems like a gray area of the REST convention.</p>
