It was first used and illustrated with families of hybrid systems. In this paper we investigate whether the STS hierarchy can account for classical families of infinite-state systems outside of timed or hybrid systems %U http://www.lsv.ens-cachan.fr/Publis/PAPERS/PDF/BS05-express.pdf %U http://dx.doi.org/10.1016/j.entcs.2006.05.007 %8 July %D 2006
