<div style="direction:ltr">I guess making the requirements in the numbered list style like FAPI makes difference. It makes it much easier for the developers to check the compliance to the spec.

<div>I reviewed the docs and there is discussion of this issue already present that I missed.<br>
<br>
Section 5 (RP-Initiated Logout) from the Session Management spec RECOMMENDS use of the id_token_hint and ends the section with a statement that the OP should ask the user if they want to logout of the OP or not.<br>
<br>
Section 8 (Security Considerations) from the Session Management spec calls out that "Logout requests without a valid 'id_token_hint' value are a potential means of denial of service; therefore, OPs may want to require explicit user confirmation before acting
upon them."<br>
<br>
Section 1 (Introduction) from the Front-Channel logout spec identifies that the spec reuses the RP-Initiated Logout functionality from the Session Management spec.<br>
<br>
All the basis are covered, though it's easy to miss. I don't know if what we have is sufficient or we should add more text.<br>
<br>
The only normative change we could make that might make things easier for RPs, now that session id is defined, would be to update Section 5 of the Session Management spec to allow for specification of the session-id instead of the id_token.<br>
<br>
Thoughts?<br>
<br>
Thanks,<br>
George<br>
