* This class works like the Java resource bundle mechanism for a named resource bundle

* This class should be extended and used in the faces-config.xml.

* Warning: The locale selection doesn't work correctly.

* @since 1.5.0
* @deprecated since 4.3.0, use standard ResourceBundles (without XML) support please.
