DBDTDHandler	A database aware Class implementing DTDHandler interface for the SAX parser to call when processing the XML stream and intercepting notations and unparsed entities
DBEntityResolver	A database aware Class implementing EntityResolver interface for the SAX parser to call when processing the XML stream and intercepting any external entities (including the external DTD subset and external parameter entities, if any) before including them.
