  Thanks for the response. At Xerox too we found that composing a cascade of rules could be not only inefficient but could also easily explode in size. We found that if the rules were to be composed with an FST encoding a lexicon, it often helped to group the compositions in a left-branching tree ( ( ( ( lexicon @ rule1 ) @ rule2 ) @ rule3 ) @ rule4 ) etc. The lexicon effectively acted as a filter that often avoided the explosion.

Yes, of course, we know that too, and most of the time people developing grammars know enough to do that by hand.
