-\begin{abstract}
-Pitts et al introduced a beautiful theory about names and binding based on the
-notions of permutation and support. The engineering challenge is to smoothly
-adapt this theory to a theorem prover environment, in our case Isabelle/HOL.
-We present a formalisation of this work that differs from our earlier approach
-in two important respects: First, instead of representing permutations as
-lists of pairs of atoms, we now use a more abstract representation based on
-functions.  Second, whereas the earlier work modeled different sorts of atoms
-using different types, we now introduce a unified atom type that includes all
-sorts of atoms. Interestingly, we allow swappings, that is permutations build from
-two atoms, to be ill-sorted.  As a result of these design changes, we can iron
-out inconveniences for the user, considerably simplify proofs and also
-drastically reduce the amount of custom ML-code. Furthermore we can extend the
-capabilities of Nominal Isabelle to deal with variables that carry additional
-information. We end up with a pleasing and formalised theory of permutations
-and support, on which we can build an improved and more powerful version of
-Nominal Isabelle.
