+ * SYNOPSIS
+ * ElementCollector(nSecurityId, nBufferId, nPriority, bToModify
+ * xReferenceResolvedListener);
+ *
+ * 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.
