Indicates if this language is to be used as default language for the partition.
One language in the partition must be nominated as the default language. The default language is an important language and has the following implications:
- When an application is invoked without nominating the required language, the default language will be used.
- Initial data dictionary, database and application development must be done in the default language. For instance, if you specify a field description via the data modeling extended file definition facilities, it is assumed that the description is in the default language.
