Hi, Even when elements make no sense when both are recorded, even then 1..1 is a problem in Archetypes. It is up to the implementer to decide to restrict 0..n further in the Template.
I suggest to make archetype as generic as possible and use almost always 0..n Implementers are exposed to Templates but NOT Archetypes.
