There was (is) a lot of confusion regarding the 5 year ROS as it was suggested in 2003 to be applicable to both PAS and the 05 pension. As T_M has said above, the ROS was (I also believe) binned in the middle of 05 following a legal challenge and thus precident set. If it does not exist, you will not find any documentation regarding it, although I do not know how far back the Pprune archives (search) go as I expect it to be the subject of discussion at that time.
AL1 I do not have the time to go through this link with a nit comb but it may be the one you need:
