Set of options for answerOption was opened up to include Value[x], where [x] belongs to ["Integer", "String", "Coding", "Reference", "Date", "Time"] . This is reflected in the Questionnaire structure but not in the definition . The definition states that answerOption is "One of the permitted answers for a "choice" or "open-choice" question." but choice type is restricted to answerOption/answerValue being valueCoding.

It is not clear how answerOption is to be used for type ValueInteger,ValueString etc
