<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I cannot tell from the writing of openid auth2.0 finalized
spec if, upon discovery relating to an OP-Identifier, claimedid and localid
MUST be absent in the XRDS response. I thus cannot tell if the RP now knows,
from that absence, that the discovery authority is making the implicit (but
formal) statement that the User entered value has type = OP Identifier.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>As the RP cannot type the identifier by itself (by normative
means), yet it must populate the openid auth request appropriate to the type,
only this critical discovery signal apparently exists ….to instruct the
RP on how to behave as an auth initiator (if it initiates).<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The problem in the writing is mostly in the last sentence, which
does not clearly indicate that the RP treatment about “what the user
entered” (as either an OP Identifier or otherwise) MUST be determined
from the discovery result. As written, it allows the RP to make its own determination
about the type …of “what the user entered”<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The writing is also not well-written more generally when addressing
the case where discovered information is used to validate an unsolicited
assertion – where there is no “user entered” data prior to
discovery initiation.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Finally, the writing does not address what happens during
validation of an unsolicited assertion, when the discovery agent indicates that
the identifier is an Op Identifier type. In my interpretation, which others do
not like, the RP SHALL perform openid auth. The RP SHALL perform as many rounds
of openid auth against one or more OP until (i) the RP determines that a
solicited assertion was received, or (ii) followup discovery about an
unsolicited assertion indicates the identifier claim is of type other than an
OP Identifier.<o:p></o:p></span></p>
