XML11NonValidatingConfiguration

public class XML11NonValidatingConfiguration extends org.apache.xerces.util.ParserConfigurationSettings implements XML11Configurable, org.apache.xerces.xni.parser.XMLPullParserConfiguration
This class is the non vlaidating parser configuration used to parse XML 1.0 and XML 1.1 documents. Xerces parser that uses this configuration is not conformant non-validating XML processor, since conformant non-validating processor is required to process "all the declarations they read in the internal DTD subset ... must use the information in those declarations to normalize attribute values, include the replacement text of internal entities, and supply default attribute values".

Allow an application to register an error event handler.

If the application does not register an error handler, all error events reported by the SAX parser will be silently ignored; however, normal processing may not continue. It is highly recommended that all SAX applications implement an error handler to avoid unexpected bugs.

Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately.
