The text part of the BrowseNames for all Nodes defined in this companion specification is specified in the tables defining the Nodes. The NamespaceUri for all BrowseNames defined in this companion specification is defined in Annex A.

If the BrowseName is not defined by this companion specification, a namespace index prefix like ‘0:EngineeringUnits’ or ‘2:DeviceRevision’ is added to the BrowseName.
