What would the contents be? A list (stack) of references to Encryption and 
Signature elements? If you add a signature or encryption, push; if you 
remove one, pop? Two issues:

1. order might not always be important (if I encrypt two sibling element 
seperately order isn't important, but won't hurt anything unless this 
deprives the application of some functionality...)
2. this information will probably then want to be signed or encrypted, we 
fold back in on ourselves and things are quite complex...?
