The output is correct, since <null> is a value. Consider using the NullAttributeMapper to remove all <null> values (i.e. change to <missing>) to get the desired result.
<empty> is a string value consisting of no characters; <null> is a special value indicating that the attribute exists but it doesn't have a valid value; <missing> indicates that the attribute does not exist.
