I believe that the issue here (and probably also related with the bindings problem we were talking the other day) is related to the impossibility of defining node identifiers to data type objects in the archetype. In theory, they are alternatives from the same type, so nothing wrong there when editing archetypes. The problem comes latter on. I believe that ADL supports this (i.e. you can say that legally in ADL), but as the reference model doesn't have a place to store that identifier you wouldn't be able to distinguish between the two alternatives in data, which in the end makes validation impossible. I think your use case is no different than when we define a domain type as a set of ordinals, which in the end are just dv_ordinal alternatives
