Understanding DIT Content Rules

DIT content rules provide a mechanism for defining the content that can appear in an entry. As with name forms, at most one DIT content rule can be associated with an entry based on its structural object class. If such a rule exists for an entry, then it works in conjunction with the object classes contained in that entry to define which attribute types must, may, and must not be present in the entry, as well as which auxiliary classes that it may include.

DIT content rules are a new feature that is available in the directory server and are not supported in the Sun Java System directory server.
