CoA can not be used to identify binding, because it is changed. 
I wrote some comments before (I replied to Nicolas)

maybe by filter information, but you can not identify two bindings if
MN does not have filter information. Filter information is not always
mandatory information. There are several approaches to maintain
filter information.

I prefer using ID to identify bindings and may associate filter
information with the IFID somewhere (maybe binding cache, maybe not).
This approach gives space for policy management and its
implementation.
