 *
 *   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 bufferred in the document
 *			wrapper component. The document wrapper component 
 *			uses this id to search the particular bufferred
 *			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.
