Try using the sample, dom.DOMCount, or dom.DOMWriter on your test case.
You will see that the test vcase is indeed invalid and the problem is that
you have not implemented an ErrorHandler, and invoked:
parser.setErrorHandler with your implementation. Simply putting
System.out.printlns
in the warning, error, and fatalError functions will show you the
validation errors.
The default of the parser is not to setErrorHandler to a specific
implementation.
We are considering setting a simple ErrorHandler that prints out the
errors as the default DOMParser implementation.
