You can check in and check out rule specifications from a Model repository that supports version control. You can undo a checkout, retrieve an earlier version, and restore a rule specification to an earlier version. When a rule specification is not under version control, the Model repository locks a rule specification while you edit it.

You can add a mapplet to a rule statement regardless of the versioned status of the mapplet. The rule statement reads the most recent version of the mapplet in the Model repository.

The rule specification does not store version information for a mapplet that you add to a rule statement. When you generate a mapplet from a rule specification, the mapplet that you generate includes the most recent version of any mapplet that you add.
