What does UBL-CR-681 mean? A UBL invoice should not include the PaymentMeans InstructionNote

Why did my invoice fail UBL-CR-681?

The cac:PaymentMeans/cbc:InstructionNote element should not be used. EN 16931 carries free-text payment terms in cac:PaymentTerms/cbc:Note (BT-20), so an InstructionNote under PaymentMeans is outside the core invoice model and validators warn on it. Move any payment instruction text to PaymentTerms.
