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

[Johannes Ernst]

Chris, I'm a little slow here, please bear with me. What's the  
reasoning for "without accessing other resources"?

I am with you if you said "we can't ask a user agent to first do a  
MIME type of XRDS". But what's the difference between adding a new ad- 
hoc link tag in the HTML to the Yadis tag in the HTML or the HTTP  
header?
