I think examples are good, but they are not enough.  We should point
to the document which defines these names somewhere, I guess in the
manual.  Where did you see that terminology ("CLDR names"), and what
is the definitive document for it?

Is the "short" part necessary?  It immediately begs the question "how
does that differ from a long name?"

Btw, the same problem exists in doc strings in emoji.el.  I tried to
improve that yesterday, but it sounds like I understood the "name"
part incorrectly, so it will need another round of changes.

Thanks.
