Well, Paul, you're the expert. Are those two correct? If they are, then I'm right about how the 
tokens work and the folks at wikipedia are wrong. I don't care whether the wikipedia folks are right 
or wrong because I don't pay wikipedia any mind because I think wikipedia is a train wreck. I want 
to be right because I want to be knowledgeable so I can help myself and so I can help other people.
