    `com.bea.p13n.management.data.repository.PersistenceException` - if an error occurs while trying to query for model data or persist model data
    `org.apache.xmlbeans.XmlException` - if an error occurs while parsing the model data

### setSegment

    void setSegment(String segmentUri,
                    com.bea.p13n.rules.model.RuleModel model,
                    boolean create,

                           org.apache.xmlbeans.XmlException

  Persists the given `RuleModel` representing a user segment. Any existing rule at the given segmentUri will be replaced by the new one.

  Parameters
    `segmentUri` - segmentUri the string URI for the desired user segment. Cannot be null.
    `model` - a `RuleModel` representing the user segment
    `create` - if true then create the user segment if it does not exist. If false then do not create the user segment if it does not exist. In both cases, an existing user segment will be replaced with the new one.
    `context` - the resource context
  Throws
    `IllegalArgumentException` - if create=false and the user segment you are trying to replace does not exist at the given segmentUri.
    `com.bea.p13n.management.data.repository.MessageException` - if an error occurs while persisting model data
    `com.bea.p13n.management.data.repository.PersistenceException` - if an error occurs while trying to query for model data or persist model data
