   * Java-specific class for dynamically loading SAX parsers.

   *
   * <p><strong>Note:</strong> This class is designed to work with the now-deprecated
   * SAX1 {@link org.xml.sax.Parser Parser} class.  SAX2 applications should use
   * {@link org.xml.sax.helpers.XMLReaderFactory XMLReaderFactory} instead.</p>
   *
   * <p>ParserFactory is not part of the platform-independent definition
   * of SAX; it is an additional convenience class designed
   * specifically for Java XML application writers.  SAX applications
   * can use the static methods in this class to allocate a SAX parser
   * dynamically at run-time based either on the value of the
   * `org.xml.sax.parser' system property or on a string containing the class
   * name.</p>
   *
   * <p>Note that the application still requires an XML parser that
   * implements SAX1.</p>
   *
   * @deprecated This class works with the deprecated
   *             {@link org.xml.sax.Parser Parser}
   *             interface.
   * @since SAX 1.0
