So it's not a normative document, but an empirical document maintained by volunteers. The introduction tells what is the difference between a domain (registered by one entity) and a subdomain (any number can be created by the same entity): If a website sets cookies for something above their domain, e.g. co.uk or org.eu the cookie would be valid on other entities' websites. Browsers use this list to prevent that. eu.org and it's non-registerable subdomains are correctly listed.
As a whole this looks a bit fragile, depending on volunteer work. Or you could say positively good old internet style: No single government or company controlling it.
The likes of uk.com and others owned by Centralnic have been around a while.
I've never been sure what to call these since they aren't (as in top) TLDs.
Does anyone know why bulgaria thought this was a good idea?

After the 2nd world war Italy just invaded south tyrol/now trentino because they mixed up the capitulation date. They still speak tyrolian there, but belong officially to Italy.
