Checking once in a while for consistency, and modifying PRD accordingly 
:-)

I implemented the change in PRD.

If you think it is better with the brackets and nobody objects...

I added the brackets back.

Maybe. I do not know. "Most" is probably a bit too strong, because they 
are not all static. But, is not it obvious that, if an ordering is 
strictly static, you can compute it once and for all, and that you can do 
that on the producer's side? Then, once you have the static ordering 
computed, you can just assign priorities to rules according to their 
position in the ordering, thus simulating the ordering (to the ones that 
do not already have a priority, that is; and, of course, you have to be 
careful that the "simulated" ordering does not interfere with the other 
priorities that may have been assigned a priori). 

Cheers,

Christian
