[QTI] Adaptive?

[Steve Lay]

Just one thing to add to this response.

Even non-adaptive items can be attempted multiple times -- indeed, the 
itemSessionControl element used in a test has a maxAttempts attribute to 
control the number of allowed attempts (for non-adaptive items) during a 
test.  The critical difference is that non-adaptive items behave the 
same at each attempt (particularly with respect to scoring).

On the other hand, *adaptive* items can behave differently at each 
attempt as Pierre describes.
