LC-2003 ACTION-883 No mention of whitelists

Proposed response

We have had considerable discussion about "allow" and "disallow" lists 
and came to the conclusion that it was preferable to discuss a proxy's 
behavior rather than its (presumed) internal method of operation. 
Instead we refer to a notion that includes allow and disallow lists 
under 4.1.5.2.

This approach allows us to specify that servers have a way of overcoming 
mis-configuration without recourse to administrative contact with any 
operator of a proxy and without specifying the exact configuration 
mechanism, which is usually not open to public inspection or evaluation.
