ErrorHandlerProxy

public abstract class ErrorHandlerProxy extends Object implements ErrorHandler
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.
