    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. */
