New issue 1207: Recommend using Alpha-3 instead of Alpha-2 [ISO3166-1]
Current specification recommends using alpha-2 format of the country code, however ICAO9303 specification advises issuers to use alpha-3 format. This is mostly followed by issuers \(notable exception is Germany that uses “D”\). The most common occurrence will be alpha-3, requiring alpha-2 means that systems will have to map from alpha-3 taken from ID documents, which seems like an unnecessary overhead.
