  39  *   NAME
  40  *  XSecParser -- a SAX parser that can detect security elements
  41  *
  42  *   FUNCTION
  43  *  The XSecParser object is connected on the SAX chain and detects
  44  *  security elements in the SAX event stream, then notifies
  45  *  the XSecController.
  46  *
  47  *   NOTES
  48  *  This class is used when importing a document.
