 * Sarissa cross browser XML library - IE XSLT Emulation (deprecated)
 * @version 0.9.7
 * @author: Manos Batsis, mailto: mbatsis at users full stop sourceforge full stop net
 *
 * This script emulates Internet Explorer's transformNode and transformNodeToObject
 * for Mozilla and provides a common way to set XSLT parameters
 * via Sarissa.setXslParameter.
 *
 * All functionality in this file is DEPRECATED, the XSLTProcessor
 * should be used instead.
