 * Sarissa cross browser XML library - IE XPath Emulation 
 * @version ${project.version}
 * @author: Manos Batsis, mailto: mbatsis at users full stop sourceforge full stop net
 *
 * This script emulates Internet Explorer's selectNodes and selectSingleNode
 * for Mozilla. Associating namespace prefixes with URIs for your XPath queries
 * is easy with IE's setProperty. 
 * USers may also map a namespace prefix to a default (unprefixed) namespace in the
 * source document with Sarissa.setXpathNamespaces

    * (moz will rezolve non-default namespaces by itself). You will need to map that
    * namespace to a prefix for queries to work.</p>
    * <p><b>Note 2 </b>: This method calls IE's setProperty method to set the
