| LocalizableResource.DefaultLocale Specifies the default locale for messages in this file. | 
| Messages A tag interface that facilitates locale-sensitive, compile-time binding of
 messages supplied from various sources.Using
  GWT.create(class)to "instantiate" an interface that
 extendsMessagesreturns an instance of an automatically
 generated subclass that is implemented using message templates selected based
 on locale. | 
| Messages.DefaultMessage Default text to be used if no translation is found (and also used as the
 source for translation). |
