Still it is not 100% same with the data from `currency.data`, but at least provides the transition logic validity, possibly for both simple and special currencies.

That's an interesting idea, I think it is possible. As you stated, the logic is different, but it would guarantee that the second run is indeed testing in the future. I'm not sure how combining a currency.properties override with the main ValidateISO4217 test will turn out though since the test should track 1 to 1 with the ISO data. Will look into it.
