Let me try and answer the first one. I don't know the answer to the  
second one.

>   </XRD>

Chances are that if the user entered, they  
wanted this to be the URL that is being displayed visually. (just  
like the OpenID convention)

> If case a. is correct, Yadis protocol can work like OpenID's delegate

Yes. That was one of the use cases we all wanted to support from the  
very Yadis beginning. Now we got more, because each Yadis service can  
have its own service endpoint, so Yadis is actually substantially  
more flexible than either LID or OpenID were before.
