* TODO check fallback semantics - fall back through default??
|
|
* Needs discussion!
|
|
*
|
|
* Regular resource bundle lookup falls back through default only when a bundle
|
|
* is opened. Once open, the lookup for an item in that bundle follows only
|
|
* the bundle's chain, without going through default.
|
|
*
|
|
* This lookup for the display strings does go through the default locale
|
|
* for the sub-item.
|
|
* It seems to be inconsistent with how the resource bundle mechanism is documented.
|
|
*
|
|
* Note also that using this mechanism (with itemKey=NULL) for the variant's
|
|
* display string, which is a top-level item and should always be available
|
|
* at least in root, is effectively the same as opening the displayLocale's
|
|
* bundle and getting the string directly from there - the fallback is the same
|
|
* (right?!).
|
|
* So, for variant's strings, one could either do that, or if the above elaborate
|
|
* mechanism is desired, one could move variant display strings into their
|
|
* own table "Variants" like the Languages and Countries tables.
