Does XProc support event-driven processing?

Hi Folks,

Does XProc support event-driven processing?

Here's an example to illustrate what I mean:

   Hey, any time during the pipeline processing, 
   if the value of <Purchase_Quantity> changes, 
   fire a step to update <Total_Cost>.

Can you think of a way to express this in XProc?
