The NodeIdentifier is used to store an identifier, where the identifier can be NodeId, Alias String, or a RelativePath.
It is semantically equivalent to the PortableNodeIdentifier as defined in 10.32, except it uses the optimization as described in F.1.2.2.
The NodeIdentifier DataType is formally defined in Table F.25.

Node |
0:NodeId |
The NamespaceIndex of the NodeId relates to the Namespaces in the ServerAddressConfDataType (see F.1.11) of the related Server. |
|
Alias |
0:String |
|
|
IdentifierBrowsePath |
0:RelativePath |
The IdentifierBrowsePath to the Node. The starting Node of the IdentifierBrowsePath shall be specified where this type is used. A NamespaceIndex in the RelativePath relates to the Namespaces in the ServerAddressConfDataType (see F.1.11) of the related Server. |
The NodeIdentifier representation in the AddressSpace is formally defined in Table F.26.
