OpenID delegate tag in the Yadis/XRDS file

For the OpenID 1.2 spec, I'd like to propose to clearly mark this tag  
as optional, just like it is optional in the (non-Yadis) OpenID spec.

The same algorithm would apply in determining which OpenID URL should  
be used at the Relying Party.

The advantage of that is that a large identity server could, if it  
wanted to, have a single X-XRDS-Location for all of the hosted  
identities, as long as they all support the same services (which is  
somewhat likely for all identities on the single host). This would  
help with caching and efficiency.
