Contained in:FormData,
Clinical data for an item group (record). The model supports repeating item groups in a single form (for example, when several previous hospitalizations are reported in one history), or within reference data.
The ItemGroupOID and ItemGroupRepeatKey are used together to identify a particular item group. This pair of values uniquely identifies an ItemGroup within the containing Form. The ItemGroupRepeatKey is present if and only if the ItemGroupDef is repeating.
ItemGroupData can also occur as reference data. In that case, the ItemGroupOID and ItemGroupRepeatKey pair must be unique within the reference data.
