The AddNodes Serviceallows specifying the Attributesfor the Nodesto add. The NodeAttributesis an extensible parameter whose structure depends on the type of the NodeClassbeing added. It identifies the NodeClassthat defines the structure of the Attributesthat follow. The parameterTypeIdsare defined in Table 153. The ExtensibleParametertype is defined in 7.17.
