Superbadges are badges that are automatically awarded after you've achieved all its sub-badges.

For example, we have a Superbadge called "Data Mining Complete" which is awarded when the learner has been awarded "Data Mining Basics" and "Data Mining Advanced".

A superbadge is expiring if at least one of it's badge is expiring.
