| It seems to me that an RST needs to specify the desired properties of the requested token in enough detail that the STS can satisfy the request without relying on out-of-band information.
As has already been pointed out, it's not enough to say that you want a SAML token.

The key part of what you quote is "conditions and restrictions on the wire formats defined by OASIS Web
Services Security [1], WS-SecureConversation [2] and WS-Trust [3] to a
specific set of typed message interchanges." well Services Security, WS-SecureConversation and WS-Trust don't depend on any formats of the tokens for wire formats, applications may but these specifications don't.

The following is from the charter for our WS-SX TC:
"WS-SecurityPolicy [4] uses the facilities of WS-Policy [5] to express
the conditions and restrictions on the wire formats defined by OASIS Web
Services Security [1], WS-SecureConversation [2] and WS-Trust [3] to a
specific set of typed message interchanges."
From this statement, there is no reason to define the WSS token
properties somewhere else. WS-SecurityPolicy has to define properties of
token in the WS-Security spec.
For example, Username Token with/without nonce or created tags should be
definable in the security policy, so that the Policy Enforcement Point
can enforce the policy accordingly.

That applies to SAML as well, i.e. SubjectConfirmation. It's meaningless
to
just say "SAML token".
I would say there should be token profiles of many of these specs, if
not
here, fine, but somewhere.
