[OpenID] XRI for OP Identifier?

[Jean-Noel Colin]

Drummond

THank you so much for your explanation. So the rule is safe, whenever  
XRI is used, CanonicalID is provided.

This canonical Id is the OP Identifier, right?

 From what I read in the specs, CanonicalID has to be used as the  
claimedId for the authentication request. But what is the meaning of  
using an OP's canonical ID as the claimedID? I would expect to have in  
the claimedID either a User ID, or the 'identifier_select' value to  
tell the OP to 'help' the user to select the appropriate ID. I don't  
understand the use of the canonical Id in case OP Id is supplied by  
the user instead of User Id

Thanks a lot
