+/**
+ * Java-specific class for dynamically loading SAX parsers.
+ *
+ * <blockquote>
+ * <em>This module, both source code and documentation, is in the
+ * Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
+ * </blockquote>
+ *
+ * <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
+ * @author David Megginson, 
+ *         <a href="mailto:sax@megginson.com">sax@megginson.com</a>
+ * @version 2.0
+ * @see org.xml.sax.Parser
+ * @see java.lang.Class
