7.3 PropertyType
The PropertyType is a subtype of the BaseVariableType. It is used as the type definition for all Properties. Properties are defined by their BrowseName and therefore they do not need a specialised type definition. It is not allowed to subtype this VariableType.
There are no References specified for this VariableType. It is formally defined in Table 73.
