The WSBaseObjectType is formally defined in Table 16. This data type is required for compatibility with WS Protocol, where the WS TagNumber is usually used to identify a WS DataPoint. In OPC UA the WS BrowseName shall be used as BrowseName for identification. Thus the WSTagNumber property is optional.
