Oops, I searched an example, and forgot to change the leading code. This should have been read as: "ca-Latn-ESCI" or "ca-ESCI". It's not importnat here, it was only an arbitrary example to show that the syntax in RFC 3066 may become ambiguous to parse. Someone says that this should be "ca-Latn-ES-CI" or "ca-ES-CI" without this problem. But isn't there (sub-country) region codes with 4 letters?
