  50  *   NAME
  51  *      XSecParser -- a SAX parser that can detect security elements
  52  *
  53  *   FUNCTION
  54  *      The XSecParser object is connected on the SAX chain and detects
  55  *      security elements in the SAX event stream, then notifies
  56  *      the XSecController.
  57  *
  58  *   HISTORY
  59  *      05.01.2004 -    Interface supported: XDocumentHandler, XInitialization
  60  *
  61  *   NOTES
  62  *      This class is used when importing a document.
