We must differentiate here a little bit. First of all, there are the 
certificate issued under the EV guidelines and the ones which are not. 
There are also differences, for example if the sub ordinated CA is 
operated by the root CA itself or by a legally and physically 
independent entity. It's important, if the root CA has a policy which 
covers those sub CAs or if the sub CA implements its own policies.

According to the changes/additions which I proposed to the Mozilla 
policy, a CA must in any case implement a policy and reasonable control 
over the sub CAs. This would cover obviously sub CAs which are 
maintained by the root *and* external ones. For EV I think it's 
appropriate that any external entity has undergone an audit (as if its a 
root itself). Frank thinks that the EV audit guidelines covers that already.

Now, if you have knowledge of sub ordinated CAs which operates not 
according to the principal above I suggest you forward this information 
even anonymously to the list or to any one of us. We could examine the 
information and decide which necessary steps should be performed. You 
shouldn't hold back such information, should you really know about it.
