An ExpandedNodeId extends the NodeId structure by allowing the NamespaceUri to be
explicitly specified instead of using the NamespaceIndex. The NamespaceUri is optional. If it
is specified then the NamespaceIndex inside the NodeId shall be ignored.
The ExpandedNodeId is encoded by first encoding a NodeId as described in Clause 5 .2.2.9
and then encoding NamespaceUri as a String.
An instance of an ExpandedNodeId may still use the NamespaceIndex instead of the
NamespaceUri. In this case, the NamespaceUri is not encoded in the stream. The presence of
the NamespaceUri in the stream is indicated by setting the NamespaceUri flag in the encoding
format byte for the NodeId.
If the NamespaceUri is present then the encoder shall encode the NamespaceIndex as 0 in
the stream when the NodeId portion is encoded. The unused NamespaceIndex is included in
the stream for consistency,
An ExpandedNodeId may also have a ServerIndex which is encoded as a UInt32 after the
NamespaceUri. The ServerIndex flag in the NodeId encoding byte indicates whether the
ServerIndex is present in the stream. The ServerIndex is omitted if it is equal to zero.
