How to use the node-opcua-constants.VariableIds.DataTypeDescriptionType_DataTypeVersion function in node-opcua-constants

function bindExtraStuff() {
        // mainly for compliance

        // The version number for the data type description. i=104
        bindStandardScalar(VariableIds.DataTypeDescriptionType_DataTypeVersion,
          DataType.UInt16, () => {
            return 0.0;
          });

        const nrt = addressSpace.findDataType(resolveNodeId(DataTypeIds.NamingRuleType))!;
        // xx console.log(nrt.toString());
        if (nrt) {
          const namingRuleType = (nrt as any)._getDefinition().nameIndex; // getEnumeration("NamingRuleType");
          // i=111
          bindStandardScalar(VariableIds.ModellingRuleType_NamingRule,
            DataType.UInt16, () => {
              return 0;
            });

          // i=112
          bindStandardScalar(VariableIds.ModellingRule_Mandatory_NamingRule,
