Stores the id of a Node, which resides within the server's address space.

The NodeId can be either:

Important: Keep in mind that the actual ID's of nodes should be unique such that no two nodes within an address-space share the same ID's.

The NodeId can be assigned to a particular namespace index. This index is merely just a number and does not represent some index within a collection that this node has any knowledge of. The assumption is that the host of this object will manage that directly.
