[QTI] question on preConditions

[Steve Lay]

Anthony,

This is an interesting use case.  If there is no responseProcessing 
element in an item then you won't need outcomes and nothing will happen 
when the student submits their responses.  (At the test level, 
outcomeProcessing might be triggered but you are not required to include 
that either.)

So there doesn't appear to be any reason why you shouldn't use 
preCondition in the way you suggest.  The only thing to point out is 
that you could even use the <correct identifier="item1.RESPONSE"/> 
instead of the baseValue element if you wanted.
