* <li>"accessed": last_access_time </li>

* <li>unique_context_name : nested object containing name:value pairs of the session attributes for that context</li>
* </ul>
* <p>
* One of the name:value attribute pairs will always be the special attribute "__metadata__". The value
* is an object representing a version counter which is incremented every time the attributes change.
* </p>
* <p>
* For example:
* <code>
* { "_id" : ObjectId("52845534a40b66410f228f23"),
* "accessed" : NumberLong("1384818548903"),
