<p class=MsoNormal>What is interesting here is that .gov could easily publish
its whitelist of OPs in such a form, rather than kludging up a root
registration authority. The XRD is signed on the fly (even though the registered
&#8220;cert&#8221; for the OP&#8217;s https endpoint is static). To scale out
the domain graph, there are chains&#8230;much as one has chains of certs and
x-certs in PKI-based domain management.<o:p></o:p></p>

<p class=MsoNormal>If anyone has an XRI Resolution client in .NET, please let
me know. In security, having your own code interwork with your own code is
typically not a strong proof of anything. <o:p></o:p></p>
