- *
- * <p>To set the DeclHandler for an XML reader, use the
- * {@link org.xml.sax.XMLReader#setProperty setProperty} method
- * with the propertyId "http://xml.org/sax/handlers/DeclHandler".
- * If the reader does not support declaration events, it will throw a
- * {@link org.xml.sax.SAXNotRecognizedException SAXNotRecognizedException}
