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. */
