What the rule checks

As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.

Test
(cac:TaxCategory/cac:TaxScheme/cbc:ID = 'VAT') and not(cac:TaxCategory/cbc:Percent)

Checked with Denmark OIOUBL 2.1 Invoice
