Languages
A language definition indicates that My MATRIXX supports that language.
You can add and remove support for subscriber-preferred languages used in announcements and notifications. My MATRIXX uses these languages to create language-specific versions of announcements to end users. You can create, delete, and edit language definitions.
Language codes must use the IETF BCP 47 format (for example, en_US, fr_FR).
Note: Language codes with sub-tags are typically denoted by hyphens in the IETF BCP 47 format.
Language definitions in My MATRIXX, however,
require the use of underscores instead.
