Thomas, In a data type like DV - in my mind- only flags can be raised that indicate the technicalities of that number. And that means "round off error" with which it is reported. All other flags are at the archetype level. Null-Flavors belong there. It is all at the semantic level, the know

Hi, A few words from a non-techie. Quantity means that what is the resulting figure expressing a quantity. Hb: 8.5 mmol/L A property of the Hb measurement can be an uncertainty. This is not an uncertainty of the figure "8.5", but of the Hb measurement where 8.5 is the correct resulting number
