up to JDF 1.5 we had the following sentence:
Note: countries are represented as two-character codes
this was removed and now it is ambiguous whether it is the 2 or 3 letter code.
|CountryCode ?||...||Country code of the Address. The 2 letter values (ALPHA-2) from [ISO/NP 3166-1:2013] SHALL be specified.
Allowed Values include are those from: [ISO/NP 3166-1:2013].
