 *
 *   SYNOPSIS

 *
 *   FUNCTION
 *  First, checks whether the SAXEventKeeper is on the SAX chain. If not,
 *  creates xml security components, and chains the SAXEventKeeper into
 *  the SAX chain.
 *  Before being chained in, the SAXEventKeeper needs to receive all
 *  missed key SAX events, which can promise the DOM tree bufferred by the
 *  SAXEventKeeper has the same structure with the original document.
 *
 *   INPUTS
 *  bRetrievingLastEvent - whether to retrieve the last key SAX event from
 *                         the ElementStackKeeper.
 *
 *   RESULT
 *  bJustChainingOn - whether the SAXEventKeeper is just chained into the
 *                    SAX chain.
 *
 *   NOTES
 *  Sometimes, the last key SAX event can't be transferred to the
 *  SAXEventKeeper together.
 *  For instance, at the time an referenced element is detected, the
 *  startElement event has already been reserved by the ElementStackKeeper.
 *  Meanwhile, an ElementCollector needs to be created before the
 *  SAXEventKeeper receives that startElement event.
 *  So for the SAXEventKeeper, it needs to receive all missed key SAX
 *  events except that startElement event, then adds a new
 *  ElementCollector, then receives that startElement event.
