That seems to be my understanding of Thomas’ suggestion – and I think that is the way to go. Then we will have a small set of “classes of null flavours” , and the detailed and local description can be added to the second field . The second field may then be of type DV_TEXT to allow both unstructured and coded values.

Is that right? 2017-01-25 13:34 GMT+01:00 Ian McNicoll <i...@freshehr.com<mailto:i...@freshehr.com>>: Hi Diego, That's a pretty good suggestion, although in that case we are really abandoning the idea of the current fixed base set of 'technical' null-flavours and allowing them to be replaced by local terms, while I was suggesting something more like the ISM_TRANSITION setup where archetype-specific 'clinical overlays' can be provided via the archetyped careflow_steps but are always associated with the underlying state_machine and current_status attribute.

This probably should work even if set of null_flavour codes is fixed. I don't know if this would be enough, but in theory it provides a workaround for all issues (except the cluster one) 2017-01-25 12:33 GMT+01:00 Thomas Beale <thomas.be...@openehr.org<mailto:thomas.be...@openehr.org>>: > > Silje has just pinged me again on the question of whether we should have an > ELEMENT.null-reason or similar attribute to accommodate specific reasons for > null_flavour being set.
