Thorsten Behrens commented on OFFICE-3940:
------------------------------------------

Hi Regina, no objections - the original proposal was just trying to be as close as possible to xmlenc-core1 - technically, there's no reason to have that extra level. Note though that (as your schema reflects), there can be more than one encrypted-key.

As for the case, again that was inspired by xmlenc-core - for that one, let's simply lowercase it, there's no further duplications of CNAMES just differeing in case.

> Currently ODF supports password-based encryption, using a user-provided string of characters to encrypt an AES session encryption key.
> That is not ideal in the context of sharing documents securely with wider audiences, since one always needs a secure sidechannel to distribute the passphrase.
> This proposal builds on top of https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/ for XML encryption, and essentially extends the ODF manifest markup with a few nodes to denote OpenPGP key material plus transport encryption for the session key
