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.
