Oh, that's right.   Sorry, it's been a long time since I looked at  
that part of the spec.   So if you send an ORO, then the server can't  
send you anything you didn't ask for in the ORO.   If you don't send  
an ORO, it can send you whatever it wants.   But if you send an ORO  
and don't request the right stuff, then what I said stands - you  
really don't want the server to volunteer options in that case.

Personally I think a client that doesn't send an ORO is going to be  
an interop nightmare, though.   Clients should really explicitly  
request the options they want.
