<div class="">Thank you very much for your help!</div>
<div class="">BTW, have you considered using an HTTP response header (see <a href="https://tools.ietf.org/html/rfc6750#section-3" class="">
https://tools.ietf.org/html/rfc6750#section-3</a>) to communicate "server-uri" and "scope" to the client?</div>
<div class="">In this case, we would not have to expose Get-System-Attributes and Get-Printer-Attributes to everyone.</div>

<div class="">(I've attached a PDF rendering of the PlantUML sequence diagram used to produce figure 4.6 "Sequence diagram for the 'oauth' IPP Authentication Method" from page 19 of 5199.10 to this reply.)</div>

Hmmm, so you are suggesting that the response in edge 11 could provide the same values that are provided via the IPP "oauth-authorization-server-uri" and "oauth-authorization-scope" Printer Description attributes mentioned in the label for edge 13?</div>
