We can. I was actually thinking about using a list of long instead, but 
frankly, I think it's easier to have 4 different ATs : when we will havz 
to debug the stuff, trust me, being able to track the 
AccessControlSeqNumber evolution only, it will be way easier than 
finding this value inside a 128 bits long BitString...
