(I hate replying to my own messages... but, well..)
Thanks for your comments @Alex. The file submitted by Verisign to satisfy Specification 5.4.3 was created using automatic translation of the English Language names of the 193 UN Member states.
[Alexander Mayrhofer] Thanks for the clarification. As i said above, it would be great to hear from ICANN what they intended with the 5.4.3 requirement - more specifically, which components of the date in the document cited in the requirement is to be used.
My point is - the requirements are vague, and hence there is no clear way to quantify the quality of a solution. Which, in turn, is bound to create interopability issues.
[Alexander Mayrhofer] I did mean 5.4.2 here, which, imho, is much more vague than the 5.4.3 requirement. It seems to me as if both https://github.com/centralnic/spec5-reserved-names/blob/master/S5.4.2.txt https://github.com/centralnic/spec5-reserved-names/blob/master/S5.4.3.txt aim at covering the "translation into the 6 UN languages" (which is Requirement 5.4.3), while none of them covers the (vague) requirement of 5.4.2...?
