Hrmm... Yes, I was advocating for layers/wrappings/peeling, but then again 
if someone adds a layer of super-encryption, the whole point of this  
transform is to create a signature that works regardless of encryptions 
done in the future (since that's impossible to know.) One can't go back and 
add a Transform to a Signature, you'd break it...
