Метод	Описание
AddReferences ( IDictionary references ) : void	This method is used to add bi-directional references to nodes from other node managers. The additional references are optional, however, the NodeManager should support them.
Browse ( OperationContext context, ContinuationPoint &continuationPoint, IList references ) : void	Browses the references from a node managed by the node manager.
