dojo.config.extraLocale is not implemented

[Rawld Gill]

define(["dojo/i18n!someModule/nls/someBundle"], //...

currently loads the bundle for the locale given by dojo.locale. It should also load the bundle for all locales given by dojo.config.extraLocale (a single locale or a vector of locales).

[Rawld Gill]

If you write...

require/define(["dojo/i18!myModule/nls/myBundle" //...

then myBundle is loaded and returned for dojo.locale. This should be changed to load localized bundles for dojo.locale + all bundles in dojo.config.extraLocale (if any), and then return the particular bundle associated with dojo.locale. Then, at any time in the future, you could request any local in dojo.locale + dojo.config.extraLocales and get the bundle synchronously via the require("<module>/nls/<locale>/<bundle>") signature.
