[OpenID] Open Challenge to webfinger and XRD

>So now I want to post my grouse no (2) with XRD.  The idea that the 
><Subject> of an XRD can be implicit or "0" is a BAD BAD BAD Idea!!

Huh. Funny you should say that. I was just thinking that following 
this thread might become dissuadingly confusing with the subject line 
identical across an unknown (but growing) number of actual 
discussions by its (implicit) description. Mind appending the grouse 
of a particular post to its subject line so we have some idea before 
reading it of what everyone is talking about?
