        In the Specification Tree Order category, there 
        is a list of CATIA attributes corresponding to the nodes in the

        This is an order by default. You can modify this order 
        by selecting a Specification Tree Node Name and clicking the Up 
        or Down button. You can reorder the whole structure, for

        nodes:
