* Locales represent a specific country and culture.

|
* for a given locale. For instance, currency number formatting is

|
* <a href="http://www.indigo.ie/egt/standards/iso639/iso639-1-en.html">ISO 639:1988</a>

|
|
* Variant strings are vendor and browser specific. Standard variant

|
* strings include "POSIX" for POSIX, "WIN" for MS-Windows, and "MAC" for

* Macintosh. When there is more than one variant string, they must
