Subject: RE: [wss] HMAC Key Derivation in UsernameToken Profile Issue
Jerry, It was my understanding that this text is going in Section 3.2 of the UsernameToken Profile and not the core.

If we want to specify the use of UsernameToken to define a key then we should do so in the UsernameToken profile, not in the core. The sentence above would be just as valid if it began "When a security token is referenced ..." In other words it is essentially vacuous. >Now, I wonder about other tokens: > When SAML Token is references from <ds:KeyInfo>, what does it mean? > Should we say something about it in SAML Token profile?
