system.opc.browseServer() nodeId?

In the system.opc.browseServer() function, one of the parameters is the nodeId. In all examples I’ve seen this is usually set to “Devices”. What are all the possible values of nodeId?

Using None gets you the root, further browse results will have a NodeId.

For tags from an OPC UA server, OPC Item Path is the NodeId.
