Errata exists for this version of the document.
The BaseDataVariableType is a subtype of the BaseVariableType. It is used as the type definition whenever there is a DataVariable having no more concrete type definition available. This VariableType is the base VariableType for VariableTypes of DataVariables, and all other VariableTypes of DataVariables shall either directly or indirectly inherit from it. However, it might not be possible for Servers to provide all HasSubtype References from this VariableType to its subtypes, and therefore it is not required to provide this information.
There are no References except for HasSubtype References specified for this VariableType. It is formally defined in Table 63.
