27: * SessionModule provides access to Session object properties.
28: * To get access to session properties use XPath syntax, e.g. to get the session
29: * id use <code>'id'</code> as the attribute name.<br/>
30: * More complex expressions with functions are also supported, e.g.:
31: * <pre>
32: * 'substring(id, 8)'
33: * </pre>
34: * will return the substring of id property of the session object.
35: * <strong>NOTE:</strong> The module does not create a new session.
