What it means
This rule checks the delivery address (BG-15) and warns if it contains a mark-care element (cbc:MarkCare inside cac:Delivery/cac:DeliveryLocation/cac:Address). This is the 'care of' or 'c/o' line of an address. EN 16931 has no separate field for it. The check applies to invoices and credit notes.
Why it matters
EN 16931 does not use a separate care-of element in the delivery address.
How to fix it
In your invoicing software, check whether the delivery address c/o line is exported in its own element. If it is needed, write it into an extra address line, for example 'c/o Jansen Logistics'. If you build the XML yourself, delete cbc:MarkCare from cac:Delivery/cac:DeliveryLocation/cac:Address and move the text into cbc:AdditionalStreetName in the same address. If delivery does not depend on it, leave it out. Recheck the corrected file.
