Thanks for your help.

But hum, I am afraid the semantics of the response processing tags are  
not very clear to me, and I did not find a lot of examples around.
First of all, how do you translate the several sucessive "if" of your  
pseudo-code? It seems that it is not possible to have two <responseIf>  
elements in the same response condition... So what is the way to go?  
several response conditions? Or one compound response condition with  
several <and> in the same responseIf element?
Then, I suppose the sum is supposed to be handled by means of the  
<sum> element, but I wouldn't mind having an example too.

So basically, if this is "not difficult" to you, an example of  
translation would be welcome!
