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.
