Why and when to perform this task
You can customize formatting behavior by passing your own formatter classes into a LocalizableTextFormatter instance through an array of optional values. This enables you to take variables other than locale and time zone into account when formatting localized text.Steps for this task
Example
The localizable-text package provides an example of a user-defined class, called LocalizableTextDateTimeArgument. This class enables date and time information to be selectively formatted according to the style values defined in java.text.DateFormat as well as constants defined within LocalizableTextDateTimeArgument itself.
