I'm not sure Diego. I guess so. We definitely need to be able to specify at template level how/if any code bindings should be handled at runtime. I suspect this might need some sort of rules that are a bit more complex than just a simple constraint.
This conversation might be a chance to tease out exactly what is required in terms of implementer guidance. I.e. In Bert's case, exactly what does the customer expect to happen.? Is ICD preferred to icpc. How is any actual code mapping carried out. I can supply some similar use cases from uk allergies work where we are transitioning to snomed but need to carry legacy codes.
