This feature should be false by default, a true value should be optional, and if a problem is encountered the error() message in the ErrorHandler should be invoked. I could be wrong about that last point if anyone wants to argue this should be a fatal error or a warning instead. However, please do let's specify which of those three methods is called. I've had a devil of a time in the past with problems one parser considers fatal, the next considers only an error, and the third relegates to warning. Also, we might want to standardize either en exception subtype or an exception message for normalization issues. I think we decided last year it was too late for most preexisting error messages, but we should be able to get out in front of this one. -- Elliotte Rusty Harold elharo@m...
