Question about <EncryptionMethod> from Dournaee, Blake on 2001-10-31 (xml-encryption@w3.org from October 2001)

Hello All,

I have a question about the schema definition for <EncryptionMethod> in
Section 5 from http://www.w3.org/Encryption/2001/Drafts/xmlenc-core/

It looks like <ds:DigestMethod> is specified as a possible child element.

Can someone explain how this works? Is this a carry-over from the previous
proposal to provide some sort of ciphertext integrity? If not, what is the
purpose of specifying a hash algorithm for the encryption method?

Thanks,
