Hi Monica,
the empty tag does not represent a null value, but just an object of length=0.
would be rendered as a null value.
If you require the empty tag (without xsi:nil-attribute) to fail validation, add a minLength=“1” to the fields restrictions in the xsd.
Then validation will fail with “… is shorter than minimum length”.
Regards,
Holger
