While reviewing various token profiles, we observed that referencing 
SAML tokens in message signatures seems awkward. 

 

SOAP Message security defines three mechanisms for ID references:

    * Local ID attributes on XML Signature elements
    * Local ID attributes on XML Encryption elements
    * Global wsu:Id attributes on elements

 

Earlier, the TC had concluded that SAML tokens using AssertionID 
violated the rules from the core specification and therefore limited 
references to using KeyIdentifiers. The recommendation is hence to use 
an STR with an STR transform or KeyIdentifier to reference SAML tokens 
from within SignedInfo. We would like to propose adding SAML AssertionID 
to the list of valid identifiers in section 4 of the core specification 
so that SAML AssertionId can be directly referenced.
