color:#1F497D">If you have an OpenID identifier that isn’t used for anything else (eg its not your blog or home page), then (in some potential future OpenID v3) a GET on
that OpenID identifier could return a XRD with its own URI in the <Subject>. It would be metadata about itself. It could point to an OP directly, eliminating the extra round-trip of going from a resource to its metadata since they are one and the same in this
case. [Mind you, I’m not sure you gain much over serving an HTML page with OpenID v1 or v2 <link>s to the OP.]<o:p></o:p></span></p>
