Decryption Transform comments

I've attached an edited version of the Decryption Transform draft, with some
minor wording and clarification changes marked in green using a .change
style.

Shouldn't the URI attribute of the Except element be required? The schema
says it is optional.

I also find the function name noDecryptNodes confusing and sugggest an
alternative: decryptIncludedNodes

I also have a question regarding transform generation. Should the document
be canonicalized before creating the Decryption Transform, as well as after?
