What it means
This rule checks that the buyer's postal address (BG-8) does not contain a care-of marking, the element cbc:MarkCare. EN 16931 gives the buyer address a street, extra address lines, a city, a postcode, a country subdivision and a country code. It has no field for a care-of marking. The rule applies to UBL invoices and credit notes alike.
Why it matters
EN 16931 does not use a separate care-of element in the buyer's postal address.
How to fix it
Look at the buyer's address in your invoicing software or customer record. If the care-of text sits in a separate field, move it into an address line (BT-50, BT-51 or BT-163) or leave it out, then export again and recheck the file. If you build the XML yourself, delete cbc:MarkCare from cac:AccountingCustomerParty/cac:Party/cac:PostalAddress and recheck the file.
