Might be a little bit to late, but I still add my thoughts to it

.
What I usually see from our suppliers is that they provide a comparison of their application and how think they meet each requirement of Part 11. Basically what you did there.
From my customer perspective:
What distinguishes a supplier that I think had a closer look at Part 11 from one that does not know much about it is that some of them point out that the responsibility lies with the customer because they don't know the final intended use and also some Part 11 requirements can't be checked by the supplier i.e. training of staff, validation, written policies that hold individuals accountable.
Some of the "big players" within the e-signature field provide some whitepapers with what I stated above. You might just want to have a look at them for orientation.
