[DDI-users] Follow up on modules

[Wendy Thomas]

You cannot include QuestionSchemes or future QuestionGroups in control 
constructs as a group. Each question gains additional information in 
relation to its use in an instrument. You must create a QuestionConstruct 
for each question used. If the question is used in multiple locations in a 
questionnaire it can be referenced multiple times or put in a sequence 
that is referenced multiple time.
