   *  variant is more powerful, more aspect oriented and more flexibile than the
   *  previous one, becuase it allows the comparsion constructs, etc. See

   *         </table>
   * </root>
   *  The values specified via "cookie-name" describe the name of the
   *  cookie, "dbcol" indicates matching database column, "nullable" means that
   *  cookie-name which is null or empty will not be included in the WHERE clause.
   *  This way you can enable accounts with empty passwords, etc. "to-session"
   *  attribute indicates under which name the value obtained from database should
   *  be stored in the session. Of course new session is created when
   *  authorization is successfull. The "type" attribute can be either string,
   *  long or double and alters the type of object stored in session. Additionally
   *  all parameters that are propagated to the session are made available to the
   *  sitemap via {name} expression. If there is no need to touch the session
   *  object, providing just one-time verification, you can specify action
   *  parameter "create-session" to "no" or "false". No values are then propagated
   *  to the sesion and session object is not verified. If you want to append
   *  attributes to the session without creating a new one, specify action
   *  parameter "append-session" to "yes" or "true".
