Surely you can only use one of them? I already have a few dozen OpenID 
identifiers, but I don't find myself accidentally entering in the wrong one.

While I agree it's easy for a user to accidentally leave out a trailing 
slash, it's much less likely that they'll accidentally type /xrds on the 
end of the URL.

Note that LiveJournal doesn't support XRDS discovery because it's still 
a pure 1.1 implementation.
