a couple of match questions

[Adam Moffett]

1) Is it possible to match on (non)membership of another class?
eg:
class "foo" {
   match if ((/some condition) /and not (member of class "xyz"));
   ...
}
I'm guessing no, because I seem to recall some discussion about match 
statements not being evaluated in any certain order.


2) Is it possible to match the /lack/ of option 82 information?
eg:
class "foo" {
   match if ((/some condition/) and (option agent.circuit-id=NULL));
   ...
}

I have some wireless APs that can provide option82 data and some other 
models that don't.  I could simplify my matching considerably if either 
of these is possible.
