BR-11 error
What this rule checks
Explanation
Within the Buyer postal address (BG-8), a Buyer country code (BT-55) is required — a two-letter ISO 3166-1 country code. Like BR-09 for the seller, this checks specifically the country code field, not the rest of the address.
How to fix it
Populate the country code inside the buyer's address block (UBL: cbc:IdentificationCode under PostalAddress/Country; CII: ram:CountryID under PostalTradeAddress) with a two-letter ISO 3166-1 code, e.g. FR.
