What does UBL-CR-189 mean? A UBL invoice should not include the AccountingSupplierParty Party Contact ID

Why did my invoice fail UBL-CR-189?

This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:Contact/cbc:ID is present: the invoice should not include an identifier on the seller contact. The seller contact (BG-6) in EN 16931 consists only of a contact point name (BT-41), telephone (BT-42) and e-mail (BT-43); a contact ID is not part of the core model. The element is not forbidden by UBL itself, but it lies outside the EN 16931 core invoice model, so remove it to keep the invoice fully conformant and interoperable.
