**Property value**

[OpcNodeReferenceCollection](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodereferencecollection/)

The [OpcNodeReferenceCollection](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodereferencecollection/) with the references which the node manager adds to the address space after the [AfterAdded](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnode/members#afteradded) event.

The node manager uses this collection itself; references added to it or removed from it by a handler of the events are taken into account.
