Information | StructureDefinition.comment | Values for comment differ: 'Scores are commonly encountered in various clinical assessment scales. Assigning a value to a concept should generally be done in a formal code system that defines the value, or in an applicable value set for the concept, but some concepts do not have a formal definition (or are not even represented as a concept formally, especially in [Questionnaires](questionnaire.html),
so this extension is allowed to appear ouside those preferred contexts. Scores may even be assigned arbitrarily during use (hence, on Coding). The value may be constrained to an integer in some contexts of use. Todo: Scoring algorithms may also be defined directly, but how this is done is not yet defined
