Thank you all for your answers. It's clear to me that Archetypes are not the place. And that openEHR does not offer any particular solution. But since we are developing a system which should provide alerts and messaging for abnormal results and "dangerous" combinations of data values, we need to solve it in some way. Any links or reference material on possible approaches to this issue would be very welcome.
