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
(cbc:PaymentMeansCode = '93') and (cbc:PaymentID = '71' or cbc:PaymentID = '75') and not(cbc:InstructionID)
