You have stumbled upon the reason this attribute should be OPTIONAL.
However, Daniel Karrenberg finds it extremely useful for some sort of
research, apparently, so it is marked MANDATORY.

As you have guessed, there are no good answers to your problem. One
possibility is to use the fact that it is MULTIPLE and list multiple
countries - so perhaps listing the country code of each of your routers.
Or you can just put something in the comments.

If you want ZZ, you can bring it up on the db-wg. It was discussed a few
years ago, but maybe we can convince them this time?
