What does BR-CL-14 mean? Country codes in an invoice MUST be coded using ISO code list 3166-1

Why did my invoice fail BR-CL-14?

Country codes in the invoice must be valid ISO 3166-1 (alpha-2) codes. This applies to party address country codes so addresses are machine-interpretable. In UBL the element is cac:Country/cbc:IdentificationCode inside postal addresses.

Official rule text

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

Common causes

Full country names ("Germany") instead of the two-letter code
Three-letter codes (DEU) where alpha-2 (DE) is expected
Non-standard codes such as "UK" instead of "GB"

How do I fix it?

<cac:Country>
  <cbc:IdentificationCode>DE</cbc:IdentificationCode>
</cac:Country>
