CCL: Use of AIM in Examining Transition States

Title: Message
Can AIM be used to evaluate bonding in a transition state structure?  After reading Bader's web site, he often refers to equilibrium structures.  Yet it seems that there is no apparent prohibition against employing AIM to studying transition states.  Since AIM is based on a physical observable and a TS is not a physical observable is it still valid to apply AIM analysis to a transition state?
