+ *
+ *   FUNCTION
+ *  construct an ElementCollector object.
+ *
+ *   INPUTS
+ *  nSecurityId -   represents which security entity the buffer node is
+ *          related with. Either a signature or an encryption is
+ *          a security entity.
+ *  nBufferId - the id of the element buffered in the document
+ *          wrapper component. The document wrapper component
+ *          uses this id to search the particular buffered
+ *          element.
+ *  nPriority - the priority value. ElementCollector with lower
+ *          priority value can't notify until all ElementCollectors
+ *          with higher priority value have notified.
+ *  bToModify - A flag representing whether this ElementCollector
+ *          notification will cause the modification of its working
+ *                  element.
+ *  xReferenceResolvedListener
+ *            - the listener that this ElementCollector notifies to.
