[OpenID] Open Challenge to webfinger and XRD

Tue Oct 20 00:06:52 UTC 2009

The XRD may not be controlled by the same individual.

I understand your argument, and I understand LRDD wanting to be able  
to separate them by having different subjects.

This is a LRDD issue not a XRD issue.

I personally think they should be separate and use the DNS name of the  
host dns:example.com where you want a URI for the host as opposed to  
the page.

However I am not part of the LRDD working group.

I wish you luck.

John Bradley
