The <lang>-<dialect> thing would appear to be the obvious choice; what's
slightly less obvious is what to do about fallback.  Three choices:
- None - i.e. I say en-gb, I either get en-gb or nothing;
- Best guess - I want en-gb, but I'm quite happy with en-us or en-au.  I
could specify en-gb and, if en-gb's not available but en-something else
is, whatever's available gets chosen for me;
- Preference list - I specify a (possibly) wildcarded list of what I
want - e.g. en-gb,en-us,en* - and whichever match comes first is what I
get.
