Saladin- That was going to be my suggestion after thinking about it more. Good luck!

That's fine. I can continue to set Castor's Unmarshaller handler as the content handler for the SAX parser, but not use it for the SAX parser's error handler. Instead I can write my own error handler class. The SAXParseException thrown by the SAX parser (i am using Apache Xerces) already reports multiple XSD validation errors. But for some reason Castor only shows the first one, and masks out the rest of the validation errors. So i can just write my own error handler class that takes the exception message string from the SAXParseException, and then parses that string for each XSD error message, and stores those parsed error messages into a collection (e.g. List).
