What does UBL-CR-304 mean? A UBL invoice should not include the TaxRepresentativeParty PostalAddress ID

Why did my invoice fail UBL-CR-304?

Within the tax representative's postal address (BG-12), EN 16931 only uses street name, additional street name, address line, city, postal code, country subdivision and country; cbc:ID on cac:PostalAddress is not part of that subset and should not appear.
