71     Default base class for SAXPath event handlers. 
72  
73     This class is available as a convenience base class for SAXPath
74     applications: it provides a default implementation for all of the
75     callbacks in the core SAXPath handler class, {@link
76     org.jaxen.saxpath.XPathHandler}
77  
78     Application writers can extend this class when they need to
79     implement only part of an interface; parser writers can instantiate
80     this class to provide default handlers when the application has not
81     supplied its own. */
