-   * This method is used by the localized name lookup methods to retrieve
-   * the localized name of a particular piece of locale data.    
-   * If the display name can not be localized to the supplied
-   * locale, it will fall back on other output in the following order:
-   *
-   * <ul>
-   * <li>the localized name in the default locale</li>
-   * <li>the localized name in English (optional)</li>
-   * <li>the localized name in the root locale bundle (optional)</li>
-   * <li>the localized input string</li>
-   * </ul>
    * <p>
-   * If the supplied key is merely the empty string, then the empty string is
-   * returned.
+   * This method is used by the localized name lookup methods to
+   * retrieve the next locale to try.  The next locale is derived
+   * from the supplied locale by applying the first applicable
+   * rule from the following:
+   * </p>
+   * <ol>
+   * <li>If the variant contains a <code>'_'</code>, then
+   * this and everything following it is trimmed.</li>
+   * <li>If the variant is non-empty, it is converted to
+   * an empty string.</li>
+   * <li>If the country is non-empty, it is converted to
+   * an empty string.</li>
+   * <li>If the language is non-empty, it is converted to
+   * an empty string (forming {@link java.util.Locale#ROOT})</li>
+   * </ol>
+   * <p>
+   * The base fallback locale is {@link java.util.Locale#ROOT}.
    * </p>
    *
-   * @param inLocale the locale to use for formatting the display string.
-   * @param key the locale data used as a key to the localized lookup tables.
-   * @param name the name of the hashtable containing the localized data.
-   * @param checkEnglish true if the method should fall back on data
-   *        from the English locale.
-   * @param checkRoot true if the method should fall back on data from the
-   *        unlocalized root locale.
-   * @return a <code>String</code>, hopefully containing the localized
-   *         variant of the input data.
-   * @throws NullPointerException if <code>inLocale</code> is null. 
+   * @param locale the locale for which a localized piece of
+   *               data could not be obtained.
+   * @return the next fallback locale to try.
