What does UBL-CR-257 mean? A UBL invoice should not include the AccountingCustomerParty Party Person

Why did my invoice fail UBL-CR-257?

EN 16931 defines a fixed set of business terms, and the UBL syntax binding marks every UBL element outside that set as not to be used. This rule (a warning) fires when the Person group under the buyer party is present: Person at cac:AccountingCustomerParty/cac:Party/cac:Person has no corresponding business term in the core invoice model. Remove the element — receivers are not required to process it, so any data placed there may be silently ignored.
