That sort of inconsistency is something we're going to have to accept 
and prepare for as we start to migrate to OpenID 2.

While the specs generally require everyone who supports 1.1 to also 
support 2, I think in practice we're going to find that some 1.1 RPs 
will fail to talk to some 2.0 OPs and vice-versa. It was my 
understanding that the switch to a new logo for 2.0 was intended to go 
some way to solve this problem.
