Sorry but this post just made me literally do an epic facepalm. I would have done a double facepalm but my hands are so large it takes only one to cover my face.
I'm not going to point out what is wrong with it. Seriously dude. If you can't figure it out yourself, then [insert rude personal insult regarding one's parents using contraceptives here].
Sorry, what I should have said was "it is stupid to have separate codes for regions of one country." England/Scotland/Wales was only an example. ISO is the same as FIFA in that sense.
