Remarks

A FormFillingDialogActivity can contain as children only those activities that implement IFormFillingElement: GetAndConfirmActivity, QuestionAnswerActivity, or ValidatorActivity.

When a FormFillingDialogActivity begins execution, it resets all its children, clearing the associated semantic item on each. The FormFillingDialogActivity then iterates through its collection of child activities, looking for the first child activity that is active (that is, one whose CanBeExecuted method returns True). When the FormFillingDialogActivity finds an active child, it executes the child activity. When the child activity returns, the FormFillingDialogActivity again iterates through its child activities, looking for an active child activity. When there are no remaining active child activities, the FormFillingDialogActivity terminates.
