+This identifier is indicated in the ISO 20022 data element `Creditor Scheme
+Identification`. The creditor can be a legal entity, or an association that
+is not a legal entity, or a person.
+Ther first two digits contain the ISO country code, the nex two are check
+digitsi for the ISO 7064 Mod 97, 10 checksum, the next tree contain the
+Creditor Bussines Code (or `ZZZ` if no bussness code used) and the remainder
+contain the country-specific identifier.
