alpha-2 and alpha-3 data violates ISO 3166-1:2020

[michael-o]

Chapter 5.1 says:

LATIN CAPITAL LETTER A through LATIN CAPITAL LETTER Z; Code elements alpha-2 and alpha-3 are formed with LETTERS,

All country codes in data is wrong because it does not use uppercase letters, but lowercase letters. Lowercase letters are used with ISO 639 for languages only.

Please correct the data.

Well, access to ISO documents isn't unfortunately free: https://www.iso.org/obp/ui/#iso:std:iso:3166:-1:ed-4:v1:en. You have to buy the full document. I have full access to most standards document on the planet thanks to my employer, but here is a free-of-charge official list from the ISO. Select country codes and hit search.
