Hi Seref,

Thanks for your interest.

The use case is about, that we need to write a set of archetypes which 
is usable as datastorage for a HL7 VMR-model in a decision-system. In 
this model, there is an ObservationResult with type ANY to hold the 
The only query-able solution we can find is to specialize the archetype 
to common situations. We have, for example an ObservationResult related 
to pregnancy, in a specialized archetype.
Depending on the kind of DataValue, there are other attributes.

The customers/users, however are not happy with this. They wonder how it 
is be done in HL7, of they have the same problem. I don't know, does 
someone know?

What would be a good solution, it would be good also if AQL had a 
solution to query the type of a datavalue, and than it would be possible 
to query the value, depending on the type, there would be another 
attribute to query.

Someone has an answer/suggestion to this?
