Topic: Permitted answers in Questionnaire

Is there a reason why there is Questionnaire.item.option to specify a list of answers as permitted answers for a "choice" question? In my opinion you could do that perfectly with a contained ValueSet with which you would have no limitations about the data type (currently only integer,date,time,string and Coding allowed on Questionnaire.item.option).

Implementer preference. A lot of implementers were quite vocal about the "overhead" involved in referencing a value set (even if it was a contained resource). As well, sometimes the choices aren't codes, but are things like numbers and dates and there's a desire to retain those data types. I understand that two ways to do the same thing adds complexity and it's possible we'll change it again once we have more implementer feedback, but that's the reason it exists as it does now.

Our implementation uses either contained valuesets, or external valuesets.
Many of our assessments have the same options for many questions, so even sharing the values internally gets lots of use by us.
Though we do appreciate the simplicty of the option set approach also.
