                                  throws org.apache.xerces.xni.XNIException

      This method notifies of the start of an entity. The DTD has the pseudo-name of "[dtd]" parameter entity names start with '%'; and general entity names are just the entity name.

      Note: Since the document is an entity, the handler will be notified of the start of the document entity by calling the startEntity method with the entity name "[xml]" before calling the startDocument method. When exposing entity boundaries through the SAX API, the document entity is never reported, however.

      Note: This method is not called for entity references appearing as part of attribute values.

      Specified by:
        `startGeneralEntity` in interface `org.apache.xerces.xni.XMLDocumentHandler`
      Overrides:
        `startGeneralEntity` in class `AbstractXMLDocumentParser`
      Parameters:
        `name` - The name of the entity.
        `identifier` - The resource identifier.
        `encoding` - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal parameter entities).
        `augs` - Additional information that may include infoset augmentations
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown by handler to signal an error.

                                throws org.apache.xerces.xni.XNIException

      This method notifies the end of an entity. The DTD has the pseudo-name of "[dtd]" parameter entity names start with '%'; and general entity names are just the entity name.

      Note: Since the document is an entity, the handler will be notified of the end of the document entity by calling the endEntity method with the entity name "[xml]" after calling the endDocument method. When exposing entity boundaries through the SAX API, the document entity is never reported, however.

      Note: This method is not called for entity references appearing as part of attribute values.

      Specified by:
        `endGeneralEntity` in interface `org.apache.xerces.xni.XMLDocumentHandler`
      Overrides:

                            throws org.apache.xerces.xni.XNIException

      The start of an element. If the document specifies the start element by using an empty tag, then the startElement method will immediately be followed by the endElement method, with no intervening methods.
      Specified by:
        `startElement` in interface `org.apache.xerces.xni.XMLDocumentHandler`
      Overrides:
        `startElement` in class `AbstractXMLDocumentParser`

      This method notifies of the start of parameter entity. The DTD has the pseudo-name of "[dtd]" parameter entity names start with '%'; and general entity names are just the entity name.

      Note: Since the document is an entity, the handler will be notified of the start of the document entity by calling the startEntity method with the entity name "[xml]" before calling the startDocument method. When exposing entity boundaries through the SAX API, the document entity is never reported, however.

      Note: This method is not called for entity references appearing as part of attribute values.

    - #### setErrorHandler

          public void setErrorHandler(org.xml.sax.ErrorHandler errorHandler)

      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.

      Specified by:
        `setErrorHandler` in interface `org.xml.sax.Parser`
      Specified by:
        `setErrorHandler` in interface `org.xml.sax.XMLReader`
      Parameters:
        `errorHandler` - The error handler.
      See Also:
        `getErrorHandler()`

    - #### getErrorHandler

          public org.xml.sax.ErrorHandler getErrorHandler()

      Return the current error handler.
      Specified by:
        `getErrorHandler` in interface `org.xml.sax.XMLReader`
      Returns:
        The current error handler, or null if none has been registered.
      See Also:
        `setErrorHandler(org.xml.sax.ErrorHandler)`

    - #### setLocale

          public void setLocale(java.util.Locale locale)
                         throws org.xml.sax.SAXException

      Set the locale to use for messages.
      Specified by:
        `setLocale` in interface `org.xml.sax.Parser`
      Parameters:
        `locale` - The locale object to use for localization of messages.
      Throws:
        `org.xml.sax.SAXException` - An exception thrown if the parser does not support the specified locale.

        `Parser`

    - #### setDTDHandler

          public void setDTDHandler(org.xml.sax.DTDHandler dtdHandler)

      Allow an application to register a DTD event handler.

      If the application does not register a DTD handler, all DTD events reported by the SAX parser will be silently ignored.

      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.

      Specified by:
        `setDTDHandler` in interface `org.xml.sax.Parser`
      Specified by:
        `setDTDHandler` in interface `org.xml.sax.XMLReader`

    - #### setDocumentHandler

          public void setDocumentHandler(org.xml.sax.DocumentHandler documentHandler)

      Allow an application to register a document event handler.

      If the application does not register a document handler, all document events reported by the SAX parser will be silently ignored (this is the default behaviour implemented by HandlerBase).

      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.

      Specified by:
        `setDocumentHandler` in interface `org.xml.sax.Parser`

        `getElementPSVI` in interface `org.apache.xerces.xs.PSVIProvider`
      Returns:
        The post schema validation infoset for the current element. If an element information item is valid, then in the post-schema-validation infoset the following properties must be available for the element information item: The following properties are available in the scope of the method that reports the start of an element: {element declaration}, {validation context}, {notation}. The {schema information} property is available for the validation root. The {error codes} property is available if any errors occured during validation. The following properties are available in the scope of the method that reports the end of an element: {nil}, {schema specified}, {normalized value},{ member type definition}, {validity}, {validation attempted} . If the declaration has a value constraint, the property {schema default} is available. The {error codes} property is available if any errors occured during validation.
