* Enumeration for localized messages formats.

* The constants in this enumeration represent the available
* formats as localized strings. These formats are intended to be
* localized using simple properties files, using the constant
* name as the key and the property value as the message format.
* The source English format is provided in the constants themselves
* to serve both as a reminder for developers to understand the parameters
* needed by each format, as a basis for translators to create
* localized properties files, and as a default format if some
* translation is missing.
* </p>
