[QTI] Modal feedback -- a better way to do this?

[Graham Smith]

Hi Bart:

In your XML example you have assigned 'null' for some outcome values,  
on the assumption I think that the rendering engine would treat 'null'  
as 'false'. I hesitate to say that this is incorrect -the specs are  
silent on the issue- but I think this assumption is dangerous. In  
JAssess at least null values in this position are rejected, and the  
result (in this case) is that your feedback with 'hide' attributes is  
never shown.

I attach a version of the XML which is more concise and follows more  
usual practise.
Because of the unusual way you have arranged the XML, I am not quite  
sure that I have interpreted what you intend correctly. But perhaps  
the attached version will point the way for you to achieve what you  
want.

Regards

Graham
