72     Default base class for SAXPath event handlers. 
73  
74     This class is available as a convenience base class for SAXPath
75     applications: it provides a default do-nothing implementation 
76     for all of the callbacks in the core SAXPath handler class, {@link
77     org.jaxen.saxpath.XPathHandler}.
78  
79     Application writers can extend this class when they need to
80     implement only part of the <code>XPathHandler</code>
81     interface. Parser writers can instantiate
82     this class to provide default handlers when the application has not
83     supplied its own. */
