1 Multiple Layer Security In determining a complete communication session between authenticating participants, a security structure that consists entirely of XML security mechanisms will be inefficient. Relying on XML Signature or XML Encryption for signing and encrypting all the messages passed could be a cumbersome and unwieldy process.

Putting the references in a manifest conveys a different validation meaning — that each reference does not need to be checked against its digest. Such a signature is called an enveloping signature. The second structure is a collection of signature properties. This is where timestamps and information such as time to sign could be placed. It could even be the place to put information to help the de-referencing of a URI.
