What does BR-CL-15 mean? Country codes in an invoice MUST be coded using ISO code list 3166-1

Why did my invoice fail BR-CL-15?

Country codes in the invoice must be valid ISO 3166-1 (alpha-2) codes. This instance of the check applies to further country code occurrences, such as the deliver-to address or origin country. In UBL these are cac:Country/cbc:IdentificationCode (address) and cac:OriginCountry/cbc:IdentificationCode (item origin).

Official rule text

Country codes in an invoice MUST be coded using ISO code list 3166-1

Common causes

• Country names or alpha-3 codes used instead of alpha-2
• "UK" used instead of "GB", or "EL" outside its VAT-prefix context
• Lowercase codes

How do I fix it?
