What does UBL-CR-218 mean? A UBL invoice should not include the AccountingCustomerParty Party PostalAddress BuildingNumber

Why did my invoice fail UBL-CR-218?

This EN 16931 rule warns when the UBL element cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:BuildingNumber is present: the invoice should not include a separate building number element on the buyer postal address. EN 16931 does not split street name and number: the house/building number is part of the address line (BT-50, cbc:StreetName), so a separate BuildingNumber element is outside 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.
