OK, Frank is right here (talking about the XSD attributes).
In the UML, the 2 classes "Variable" are identical, but in the Schema 
one global type for the Variable class was created.
In the XSD, both the taskReference and the modelReference have to be 
added to the variable global type... which also answers the question why 
they are optional - one of the references is for use of the variable 
element in ChangeMath, the other one is for use of the variable element 
in Task and DataGenerator...
... which is why Nicolas probably is right saying that we have to fork them
... or we could check whether we want to go back to using 
modelReferences in the DataGenerator class instead of using the 
taskReference - which I would prefer.
