Reported by @karlvestin:

OPC UA servers may change the AddressSpace at run-time. There are also OPC UA Services defined (AddNodes, DeleteNodes), so that clients can request the server to change its AddressSpace.
See https://reference.opcfoundation.org/Core/Part4/v105/docs/5.7

The Device Support should support such changes by trying to re-attach nodes that received BadNodeIdUnknown replies before.

The server is supposed to send specific events to announce changes in the AddressSpace.
See https://reference.opcfoundation.org/Core/Part3/9.32.7/

The Device Support should receive such events and try to re-attach disconnected nodes when appropriate.
