This issue was brought up because the signing algorithm assumes there  
is only one parameter of a given name.

If the SIGNALL algorithm took all the name / value pairs and sorted  
them by byte order, then concatenated them, this would not be an  
issue. If there is a need for multiple parameters in a message in the  
future, it can be done, and this algorithm means the openid.signed  
parameter is not needed. That would seem to be a simpler algorithm  
and solution.
