While I fully understand the limitation of locales as they are currently
defined, I'm very doubtful that the situation can be improved in a near
future, given that:

1. It is hardly possible to define *scientifically* what is a locale. Even
the candidates for the *base* have shaky definition (e.g. language,
region -why country?-, time zone, ...).

if we pass this hurdle:

2. It is hardly possible to decide what is a *valid* locale (This is where
David started). Shall we base it on the number of people it targets? In that
case for example a locale such as sp_US (22 million people) should be *more
valid* than fr_CA (7 million people). How can we prevent the lurking
combination explosion? Some quick maths show that technically there are more
locale candidates than character candidates for Unicode (dooh!).

if we pass this hurdle:

3. It will be impossible for each application to support ALL valid locales.
Then how the fall back mechanisms should work? Say that the sp_US locale is
not present in my system, shall I default to Spain Spanish or English US? I
guess you will say a bit of both... (side question then, how to prevent Mr
QA guy from going postal?)

if we pass this hurdle:

4. As Tex pointed out it is not even obvious what locales are to be used
for. Some candidates include Selecting the content to display, formatting
rules, collation rules, time zone, calendar, address format, units of
measure, currency (shall we limit to one?)  but I'm sure we can find much
more (e.g. basic privacy rules, sales tax information, ...).

and last but not least:

5. It won't be an easy thing to make it simple to use, so at least people be
tempted to look at it. How to make it a stantard so our locales will be
portable to all platform? Shall a "Unilocale consortium" be created :).

The point of these questions is certainly not to get answers, but to show
that without a given application framework it is impossible to get a closure
on this topic. Sorry if this is bad news for some but I don't really see how
custom coding could be avoided  in the forseeable future for application for
which the current locales are not enough (this is what I believe trigered
this entire discussion).

Don't take me wrong, I'm all for a better world but to join Martin Duerst
comment, rather than critizing current models why not present ideas on how
they could be improved? For those who have implemented their own solutions,
why not make them into an open source project (Universal Locale Components?)
to try to get it to become a de-facto standard like tz? - I'll be the first
to advertise it-.

My 2 Euro cents,

Thierry.
