I over spoke... err... typed.

I assume they're in there in conjunction with the nonce to protect  
replay attacks which would let a MitM between the RP and the IdP  
falsely authenticate a URL, right? And (depending on how long the IdP  
chooses to maintain them, when I read the spec I was thinking that the  
association would generally be good for weeks) to authenticate the IdP  
against DNS spoofing?

Of course HTTPS for that connection makes them redundant. And in my  
RP, I'd probably ignore them.
