OpenID Login Page Link Tag (was RE: PROPOSAL: OpenID FormClarification (A.4))

[Drummond Reed]

In this case the link tag just points to the RP's OpenID login page, which
enables a browser to have a button that initiates OpenID login at the site
(provided you've been there before).

However the RP could have its own Yadis XRDS file, and the link tag could
point to that to discover this same info. That would work even when you're
not at the site. Is that what you mean?

Isn't this a case where the Yadis infrastructure should be used  
instead of Yet Another Link Tag?
