XML validation: fail-slow and capture all the errors

see here for the whole story:

Validating a XML document capturing ALL the validation errors is a bit roundabouthish:

first you must create a ErrorHandler:

public static class XMLValidationErrorHandler implements ErrorHandler {
  List errors = new ArrayList();

  public void warning(SAXParseException ex) {
   errors.add(new ValidationError(ex.getLocalizedMessage()));
   logger.error("ErrorHandler warning " + ex.getLocalizedMessage());
  }

  public void error(SAXParseException ex) {
   errors.add(new ValidationError(ex.getLocalizedMessage()));
   logger.error("ErrorHandler error " + ex.getLocalizedMessage());
  }

  public void fatalError(SAXParseException ex) {
   errors.add(new ValidationError(ex.getLocalizedMessage()));
   logger.error("ErrorHandler fatalError " + ex.getLocalizedMessage());
  }

  public List getErrors() {
   return errors;
  }
 } 

and then assign it to the unmarshaller:

List errors = new ArrayList();
byte[] bytes = xmlAsString.getBytes();
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
Source paramSource = new StreamSource(bais);

Schema schema = unmarshaller.getSchema(); 
Validator validator = schema.newValidator();

XMLValidationErrorHandler errorHandler = new XMLValidationErrorHandler();
validator.setErrorHandler(errorHandler);

validator.validate(paramSource);
errors = errorHandler.getErrors();

I really feel that things should be easier than that...
