To add to what Ken and Markus said: like many other identifiers, there are
a number of different categories.
1. *Ill-formed: *"$1"
2. *Well-formed, but not valid: *"usx". Is *syntactic* according to
http://unicode.org/reports/tr51/proposed.html#def_emoji_tag_sequence,
but is not *valid* according to
http://unicode.org/reports/tr51/proposed.html#valid-emoji-tag-sequences
.
3. *Valid, but not recommended: "usca". *Corresponds to the valid
Unicode subdivision code for California according to
http://unicode.org/reports/tr51/proposed.html#valid-emoji-tag-sequences
and CLDR, but is not listed in http://unicode.org/Public/emoji/5.0/.
4. *Recommended:* "gbsct". Corresponds to the valid Unicode subdivision
code for Scotland, and *is* listed in
http://unicode.org/Public/emoji/5.0/.
As Ken says, the terminology is a little bit in flux for term
'recommended'. TR51 is still open for comment, although we won't make any
changes that would invalidate http://unicode.org/Public/emoji/5.0/.
====
I would also encourage people to look at the slides on
http://unicode.org/emoji/, together with the speaker notes, since some of
those slides present this very issue. I'm sure the people on this list will
have some useful comments for improvements.
Another item: with Tayfun's help, we updated
http://unicode.org/press/emoji.html. If people have any feedback on other
articles that should be on that list, please let us know...
