Subject: [QTI] QTI multiple response question with empty answer



Hi, folks.

How can I have a multiple response question where the correct answer
is to not tick any of the boxes?

I have some example QTI files on the web:
http://users.ecs.soton.ac.uk/bjn/multipleresponse1.xml
http://users.ecs.soton.ac.uk/bjn/multipleresponse2.xml
http://users.ecs.soton.ac.uk/bjn/multipleresponse3.xml

multipleresponse1.xml is a question where the correct response is to
tick the first box. That's fine.

multipleresponse2.xml was how I expected to show that the correct
response is to tick no boxes -- an empty correctResponse tag. It
doesn't validate (using JQTI):
Error: Not enough children: value. Expected at least: 1, but found: 0
(assessmentItem:mcr_598->responseDeclaration:RESPONSE->correctResponse)

multipleresponse3.xml was another attempt -- the responseDeclaration
tag is empty. This validates but when I load it into QTIEngine
(http://qtiengine.qtitools.org <http://qtiengine.qtitools.org/> ) it doesn't accept no ticked boxes as a
correct answer.

I wonder if someone can point me in the right direction?

Thanks
