/**
|
||
|
|
* There are basically two kinds of alias in CLDR:
|
||
|
|
* 1. locale alias e.g.
|
||
|
|
* in xml, <alias source="locale" path="......"/>,
|
||
|
|
* in gernated JSON bunle, xxxx@localeAlias:{'target':'xxx', 'bundle':'xxxx'}
|
||
|
|
* 2. other locale alias e.g.
|
||
|
|
* in xml, currently only like <alias source="fr" path="//ldml"/>
|
||
|
|
* #1 is supported by this 'alias.js',
|
||
|
|
* #2 is covered by 'specialLocale.js' and may need enhancement for future CLDR versions.
