A conforming model must provide the motivation element types and keep their defined meanings apart: stakeholder, driver, assessment, goal and outcome for interests, conditions and intended end states, alongside principle applying to any system in a context, requirement applying to the system the architecture describes, constraint limiting the architecture or its realization, and meaning and value for knowledge and relative worth. A model must not use one of these types in place of another whose definition differs.
