/**
* Wraps {@link XMLErrorHandler} and make it look like a SAX {@link ErrorHandler}.
*
*
* The derived class should override the {@link #getErrorHandler()} method
* so that it will return the correct {@link XMLErrorHandler} instance.
* This method will be called whenever an error/warning is found.
*
*
* Experience shows that it is better to store the actual
* {@link XMLErrorHandler} in one place and looks up that variable,
* rather than copying it into every component that needs an error handler
* and update all of them whenever it is changed, IMO.
