/**

   Default base class for SAXPath event handlers. 

   This class is available as a convenience base class for SAXPath
   applications: it provides a default do-nothing implementation 
   for all of the callbacks in the core SAXPath handler class, {@link
   org.jaxen.saxpath.XPathHandler}.

   Application writers can extend this class when they need to
   implement only part of the <code>XPathHandler</code>
   interface. Parser writers can instantiate
   this class to provide default handlers when the application has not
   supplied its own. */
