This factory returns an evaluator that can evaluate group memberships. Specifically, the returned class inherits from the evaluator provided by PersonEvaluatorFactory. This means that its syntax semantics are identical except for the <attribute> element. Its semantics are overwritten to support only a single mode, memberOfoverwritten to support 2 modes (as of uP 2.5.1), memberOf and deepMemberOf. memberOf will test for membership of the named group only, whereas deepMemberOf will also test for membership in groups contained by the named group. The name attribute should contain the name of the group with matching case. The value attribute is not used. The News fragment in the default dlm.xml file in the portal uses this factory to push the news fragment to members of the Students group who are not also members of the Faculty group.
