  * LanguageImpl <br>
 41   
  * Okay, base Language really has nothing to really do at all with language per
 42   
  * se. It actually represents the locallized <code>title</code> and
 43   
  * <code>short-title</code> attributes of a portlet's definition. It also
 44   
  * contains a resource bundle for the specifc locale. <br>
 45   
  * TODO: org.apache.pluto.om.common.Language should be seperated into TODO a
 46   
  * Language class that just contains the resource bundle and TODO a Title class
 47   
  * that contains a localized title and short title.
