 * 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.
