Hi Joseph,
http://www.w3.org/Encryption/2001/Drafts/xmlenc-core/
$Revision: 1.86 $
---------------------------------
2.2.1 EncryptedData with Symmetric Key (KeyName)
[s4] <ds:KeyName>
John Smith
</ds:KeyName>
Should this be
[s4] <ds:KeyName>John Smith</ds:KeyName>
? I mean in 2.2.2 EncryptedKey, there is a reference to
[t13] <ds:KeyName>John Smith</ds:KeyName>
---------------------------------
Another comment is in Section 2.2.2 EncryptedKey, there is the following
sentence:
[t15] The CipherData's CipherValue is
an octet sequence that is encoded (e.g.,
padded) by a referring encrypted object's
EncryptionMethod.
From what I see, the Padding which was mentioned as example is part of the
EncryptionMethod, so the encoding sequence is
1. serialization to octets
2. in case of EncryptedData nonce handling
3. encryption
3.1 padding
3.2 block cipher application
4. base64 encoding
so padding is am integral part ot the encryption and cannot be used as
example for encoding.

Christian
