The OP is free to call the user identity whatever it likes in its UI. 
For example, LiveJournal could reasonably look at one of its own URLs 
like http://frank.livejournal.com/ and refer to the user as "frank".

In version 1.1 of OpenID, which is what is widely deployed today, the OP 
wasn't actually ever sent the claimed_id. The thinking behind this was 
that OPs would then be unable to "tell" that they are being delegated 
to, and thus can't make delegation a premium service or whatever.

However, as you've almost certainly seen, the claimed_id is now included 
in the OpenID 2.0 authentication requests in order to support some new 
features in 2.0, and so OPs could now start to use the claimed_id in 
their UI if they wish -- particularly in the XRI case you noted.
