The BaseDataVariableTypeis a subtype of the BaseVariableType. It is used as the type definition whenever there is a DataVariablehaving no more concrete type definition available. This VariableTypeis the base VariableTypefor VariableTypesof DataVariables, and all other VariableTypes ofDataVariables shall either directly or indirectly inherit from it. However, it might not be possible for Serversto provide all HasSubtype Referencesfrom this VariableTypeto its subtypes, and therefore it is not required to provide this information.
There are no Referencesexcept for HasSubtype Referencesspecified for this VariableType. It is formally defined in Table 63.
