The derived class should override the getErrorHandler() method
so that it will return the correct XMLErrorHandler instance.
This method will be called whenever an error/warning is found.
Experience shows that it is better to store the actual
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.
