Indeed. "Be aware that there is an EU directive that says "Made in EU" must be
put on CDs in some cases even if it is released in only one country." <- quote from Places issued RYM guideline
Regarding this, RYM, Discogs and MusicBrainz have different criteria, say, when it comes to release country or issuing countries. MBz is the more "relaxed" of them all, on the other extreme, RYM is very "pedantic": I've noticed that once they see Performing rights societies (or copyright collection societies Wikipedia they immediately associate that release to PRS country, which isn't entirely correct.
Overall, the guideline is quite well written, and also notice the 4 conditions a release must satisfy to be issued as a European release.
