/** Another RDF Parser.
 * To load an RDF file:
 * <ol>
 * <li>Create an ARP.</li>
 * <li>Set its handlers, by calling the {@link #getHandlers}
 * method, and then.</li>
 * <ul>
 * <li>Setting the statement handler.</li>
 * <li>Optionally setting the other handlers.</li>
 * </ul>
 *
 * </li>
 * <li>Call a load method.</li>
 * </ol>
 * <p>
 * Xerces is used for parsing the XML.
 * The SAXEvents generated by Xerces are then
 * analysed as RDF by ARP.
 * Errors may occur
 * in either the XML or the RDF part, see
 * {@link ARPHandlers#setErrorHandler} for details
 * of how to distinguish between them.</p>
 * <p>
 * For very large files, ARP does not use any additional
 * memory except when either the {@link ExtendedHandler#discardNodesWithNodeID}
 * returns false or when the {@link AResource#setUserData} method has been
 * used. In these cases ARP needs to remember the <code>rdf:nodeID</code>
 * usage through the file life time. </p>
 * <p>See <a href="/documentation/io/index.html">ARP documentation</a> for more information.</p>
