I concur with Uli - much more clear! And thanks for the legwork, as always.

<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;">Continuing this thread concerning resource URIs and the Same Origin policy that is used in web browsers for this sort of thing:<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;">1. Web Browsers support a HTTP extension called Cross-Origin Resource Sharing (CORS), which is documented here:<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"> <a href="https://fetch.spec.whatwg.org/#http-extensions" style="color: rgb(70, 120, 134); text-decoration: underline;">https://fetch.spec.whatwg.org/#http-extensions</a><o:p></o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"> The kicker is that this extension is used to allow PUT and POST requests - GET, HEAD, and OPTIONS requests are *not* limited in any way. So it doesn't look like CORS is a solution
for IPP resources.<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;">2. Sharing OAuth bearer tokens across domain names probably won't work in the general case, either, because the resource URI passed in the authorization request will be different...<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;">Given these discoveries, I think we just need to reword the conformance requirements to be explicitly clear, something like:<o:p></o:p></div>
