// SAX2 DefaultHandler Class.
//
// Note that the function of this class has changed since
// the old SAX release, where it was a proprietary extension
// to the SAX interface. SAX2 now defines its own DefaultHandler
// interface, so this class had to change. The old functionality
// of the CDefaultHandler is now available from the CAnyHandler
// class.

	//: Default base class for SAX2 event handlers. 
	//+ This class is available as a convenience base class for SAX2 applications: 
	//+ it provides default implementations for all of the
	//+ callbacks in the four core SAX2 handler classes:
	//+      EntityResolver 
	//+      DTDHandler 
	//+      ContentHandler 
	//+      ErrorHandler 
	//+ Application writers can extend this class when they need to implement only 
	//+ part of an interface; parser writers can instantiate this
	//. class to provide default handlers when the application has not supplied its own.
