EncryptionMethod in XMLEnc and DigestMethod in XMLDSig

A minor issue but probably it's worth to fix it: the EncryptionMethod
in XMLEncryption and DigestMethod in XMLDSig both have the same meaning:
algorithm selection. However, EncryptionMethod is *optional* element and
DigestMethod is *required*. From my point of view it is inconsistent.
Either both should be required or both should be optional. I would 
prefer the second (both optional) since application can have this
information from the context.
