What it means
The invoice can name the seller's tax representative (BG-11), the person or company the seller has appointed to account for VAT on its behalf. In UBL a postal address can carry the name of a person or department to whose attention mail is directed, in its own element. EN 16931 has no separate field for it, because the address is given as address lines, city, postcode, country subdivision and country. The rule fails when cac:TaxRepresentativeParty/cac:PostalAddress/cbc:MarkAttention is in the file at all, even if empty.
Why it matters
EN 16931 does not use a separate attention field for the tax representative's address. Attention text can be included in an address line if needed.
How to fix it
If you need the attention text in the address, include it in an address line, such as the second address line (BT-65), cbc:AdditionalStreetName, for example 'FAO Finance'. Remove cbc:MarkAttention from cac:TaxRepresentativeParty/cac:PostalAddress and recheck the corrected file.
