Thanks! As for the DH and RSA-OAEP with SHA256 and SHA512, I am wondering if
couldn't decrypt them or you haven't tested them.

My intention is that if you do the decrypt and replace, the type information
should be needed.
In other words, it should cause you trouble when you replace the EncryptedData
element with
the decrypted data if the the type attribute is not set correctly.

I will send a report soon. I will also add more samples for anything else
in the future.
