    - #### warning

          public void warning(java.lang.String domain,
                              java.lang.String key,
                              org.apache.xerces.xni.parser.XMLParseException exception)
                       throws org.apache.xerces.xni.XNIException

      Reports a warning. Warnings are non-fatal and can be safely ignored by most applications.
      Specified by:
        `warning` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
      Parameters:
        `domain` - The domain of the warning. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this warning.
        `key` - The warning key. This key can be any string and is implementation dependent.
        `exception` - Exception.
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

    - #### error

          public void error(java.lang.String domain,
                            java.lang.String key,
                            org.apache.xerces.xni.parser.XMLParseException exception)
                     throws org.apache.xerces.xni.XNIException

      Reports an error. Errors are non-fatal and usually signify that the document is invalid with respect to its grammar(s).
      Specified by:
        `error` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
      Parameters:
        `domain` - The domain of the error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this error.
        `key` - The error key. This key can be any string and is implementation dependent.
        `exception` - Exception.
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

    - #### fatalError

          public void fatalError(java.lang.String domain,
                                 java.lang.String key,
                                 org.apache.xerces.xni.parser.XMLParseException exception)
                          throws org.apache.xerces.xni.XNIException

      Report a fatal error. Fatal errors usually occur when the document is not well-formed and signifies that the parser cannot continue normal operation.

      Note: The error handler should always throw an `XNIException` from this method. This exception can either be the same exception that is passed as a parameter to the method or a new XNI exception object. If the registered error handler fails to throw an exception, the continuing operation of the parser is undetermined.

      Specified by:
        `fatalError` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
      Parameters:
        `domain` - The domain of the fatal error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this fatal error.
        `key` - The fatal error key. This key can be any string and is implementation dependent.
        `exception` - Exception.
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

    - #### createSAXParseException

          protected static org.xml.sax.SAXParseException createSAXParseException(org.apache.xerces.xni.parser.XMLParseException exception)

      Creates a SAXParseException from an XMLParseException.

    - #### createXMLParseException

          protected static org.apache.xerces.xni.parser.XMLParseException createXMLParseException(org.xml.sax.SAXParseException exception)

      Creates an XMLParseException from a SAXParseException.

    - #### createXNIException

          protected static org.apache.xerces.xni.XNIException createXNIException(org.xml.sax.SAXException exception)

      Creates an XNIException from a SAXException. NOTE: care should be taken *not* to call this with a SAXParseException; this will lose information!!!
