Represents an OPC UA node using a namespace URI instead of a namespace index,
so that node identifiers can be persisted and resolved across OPC UA
sessions.
Note: a namespace index managed by an OPC UA server might point to different
namespace URIs in different client sessions. For this reason, we use
namespace URIs to identify nodes.
A string in the format "=" as defined
by OPC UA. For example, "s=Device001.Tag4711" (string), "i=1234"
(integer), "g=01cb879b-ddd7-4edc-909c-37f23ff9e6c3" (Guid/UUID),
"b=FFA50037" (opaque/binary byte string).
Optional namespaceUri
namespaceUri:string
Specifies the namespace URI on the OPC UA server (optional). If omitted,
defaults to the standard OPC UA system namespace with index 0
("http://opcfoundation.org/UA/").
