Existing Wording: This expression serves the same purpose as the initial.value on Questionnaire.item, except that rather than specifying a fixed value, the value is calculatable. The value is set on initial creation of the QuestionnaireResponse or upon the question first becoming enabled. If used for a readOnly and/or hidden element, the expression essentially calculates a 'fixed value' for the element. If used for an editable element, this extension sets the initial value for the element. However, the value may subsequently be overridden by the user authoring the response.

Comment:

I assume, this overwrites a fixed initalValue that is specified in the item? If so, please specify as such.
