Well no.  Either you know the EncryptionMethod for the EncryptedKey
implicitly 
or else it is provided by the EncryptionMethod element within the
EncryptedKey element. EncryptionMethod information for an EncryptedData
isn't relevant.

Ok, so this means that the type of that raw data is separated from it.
If 
you have an odd EncryptedKey laying about, you process it, get the raw
data 
and are not sure what EncryptedData it applies to, you won't know what
type 
it is. Right?
