title: Is a list/array valid JSON?
body: <p>I wish to write a webservice which serves lists of JSON objects.  Is it valid JSON to return the following:</p>
  
  <pre><code>[
    {"keyA1":"valA", "keyB1":"valB"}
   ,{"keyA2":"valA", "keyB2":"valB"}
   ,{"keyA3":"valA", "keyB3":"valB"}
  ]
  </code></pre>
  
  <p>Or is the "right" way to do it to put it in a single object to return:</p>
  
  <pre><code>{"elements":[
     {"keyA1":"valA", "keyB1":"valB"}
    ,{"keyA2":"valA", "keyB2":"valB"}
    ,{"keyA3":"valA", "keyB3":"valB"}
  ]}
  </code></pre>
