<div>Hi Axel,</div>
<div><br>
</div>
<div>I have just read it and I think that it was what we agreed, only pointing out that in the sentence “If the value of the signatures’s “alg” parameter is “none” then another method of Client authentication MUST be used as described in Section 9…. I think
we should add the case where the Request object is not used as well, in order to clarify that not only requests using the “Request Objetc” must be authenticated but also those using query parameters.</div>
<div><br>
</div>
<div>More or less, something like this…</div>
<div><span style="font-family: verdana, helvetica, arial, sans-serif; font-size: 13.3333px; font-variant-ligatures: normal; orphans: 2; widows: 2;"> If the value of the signature’s “alg” parameter is “none” or
<b><i>the Request object is not used.</i></b> then another method of Client authentication MUST be used as described in Section 9 on </span><a href="https://xml2rfc.tools.ietf.org/cgi-bin/xml2rfc.cgi?Submit=Submit&format=ascii&mode=html&type=ascii&url=https://bitbucket.org/openid/mobile/raw/tip/draft-mobile-client-initiated-backchannel-authentication.xml?at=default#OpenID.Core" style="text-decoration: none; font-family: verdana, helvetica, arial, sans-serif; font-size: 13.3333px; font-variant-ligatures: normal; orphans: 2; widows: 2;">[OpenID.Core]</a><span style="font-family: verdana, helvetica, arial, sans-serif; font-size: 13.3333px; font-variant-ligatures: normal; orphans: 2; widows: 2;">.
CIBA is allowing the same Client authentication methods for the Authorization Endpoint that OpenID.Core uses for the Token Endpoint. </span></div>

</div>
<div>What do you reckon?</div>
