Yes, but this creates a chicken/egg scenario with the specification (of SAML
in this example), and it's not at all a given that if you were going to
"solve" this by altering the signature profile or creating a new one that
you wouldn't solve it by punting on XML Signature altogether and just use a
"sign the blob" approach as an enveloping signature.
