[FIG[
[7] 
>In this model, a locale is an identifier (id) that refers to a set of user preferences that tend to be shared across significant swaths of the world. Traditionally, the data associated with this id provides support for formatting and parsing of dates, times, numbers, and currencies; for measurement units, for sort-order (collation), plus translated names for time zones, languages, countries, and scripts. The data can also include support for text boundaries (character, word, line, and sentence), text transformations (including transliterations), and other services.
