And indeed should I persuade ISO that my back garden was a sovereign state
RFC3066 would allow en-JG. I would still speak en-IE though. Any use of
en-JG would be wrong because there is no such language and it hence
identifies something that doesn't exist, a bit like a null pointer.

IETF registration is intended to cover languages and dialects that do exist
but which don't have an unambiguous identifier from the range automatically
