In case ii) I think (but could be wrong) that a subject represented only by
a security token was intended to be expressed as only SubjectConfirmation.
Is it useful to have a confirmation method perhaps that says the
confirmation data will be a STR?

I note current specs only identify Target in a vague way via Audience. I
personally like the simplicity. Of course encryption also provides some
degree of targeting.

Confidentiality of...?

Would like to in general see us first settle on the basic use
cases/semantics we want to support in the AuthnRequest protocol (or
protocols) and what message bits are needed. Then a separate discussion
could be had on where WSS STR's fit or don't fit in the current schema as a
means of expressing some of those pieces. Just a thought.
