Now consider the general case, where more that one GF-rule or agreement process must be appealed to in the analysis of a given sentance. Since we are purposely focusing on processes that crucially involve grammatical functions, the output of any process will depend on the GF-structure that it gets as input, which in turn will depend on which (if any) processes have happened before it. To put this another way, this process stand in potential "feeding" and "bleeding" relationships to one another. Whether we actually observe "feeding" or "bleeding" between the two rules will give us syntactic evidence concerning the order in which they must have applied.
