[ACTION 891] clarify statement on testing interface

As per the action, the intent of section 5 must be clarified.

I propose modifying the current paragraph as follows:

-----
The operator of a content transformation proxy SHOULD
make available an interface through which the functions of
the proxy can be exercised. The operations possible
through this interface MUST cover those necessary to
settle the outcome of all conformance statements listed in
section B.

The interface MUST be reachable from terminals with
browsing capabilities connected to the Web via a
conventional Internet access environment at the tester's
premises; accessing the interface MAY necessitate
adjusting standard Web browsing configuration 
parameters -- such as specifying a proxy IP address and
port on a desktop browser, or activating a WAP setting on
a mobile browser.
-----

Which begs the question: do operators already have their
CT-proxies available on the Web for the purpose of
external checking of how they work?
