+/**
+ * <p>
+ * This is the superclass of all the {@link Locale} service
+ * provider interfaces or SPIs.  The locale SPIs are used
+ * to allow for the provision of additional support for
+ * locale-specific data.  The runtime environment has its
+ * own collection of locale data, but these interfaces allow
+ * this to be extended by external classes.
+ * </p>
+ * <p>
+ * Service providers are created as concrete implementations
+ * of these interfaces, and accessed using the extension
+ * mechanism, realised by {@link ServiceLoader}.  When a factory
+ * method of one of the locale-specific classes (such as
+ * {@link java.text.DateFormatSymbols} or {@link java.util.Currency})
+ * is called, the runtime environment is first asked to
+ * provide data for the specified locale.  If the runtime
+ * environment fails to provide this, then the offer is
+ * made to service providers which implement the appropriate
+ * interface.
+ * </p>
+ * <p>
+ * Each provider implements the method specified by this
+ * class, {@link #getAvailableLocales()}.  This method is
+ * called first to determine whether the provider will be of
+ * any use in providing data for the specified locale.  If
+ * a provider is found to be capable, then a more specific
+ * method appropriate to the class requiring the data will
+ * be called.  In the case of {@link java.text.DateFormatSymbols},
+ * this would be
+ * {@link java.text.spi.DateFormatSymbols#getInstance(Locale)}.
+ * </p>
+ * <p>
+ * If neither a service provider nor the runtime environment
+ * itself can fulfill the request, a fallback procedure is
+ * engaged.  The locale is modified by applying the first
+ * applicable rule:
+ * </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.</li>
+ * </ol>
+ * <p>
+ * The modified locale is then used to start the same
+ * process again.  The root locale (@link java.util.Locale#ROOT}
+ * must be supported by the runtime environment in order
+ * to terminate this cycle.
+ * </p>
+ * <p>
+ * Note that any names returned by the providers may
+ * be <code>null</code>.  Returning a <code>null</code>
+ * name is considered equivalent to not supporting a
+ * particular locale.
