OK, proposed patch at 
<http://trac.tools.ietf.org/wg/httpbis/trac/attachment/ticket/296/296.diff>.

The new text would be:

8.2.4.  203 Non-Authoritative Information

    The representation in the response has been transformed or otherwise
    modified by a transforming proxy (Section 2.3 of [Part1]).  Note that
    the behaviour of transforming intermediaries is controlled by the no-
    transform Cache-Control directive (Section 3.2 of [Part6]).

    This status code is only appropriate when the response status code
    would have been 200 (OK) otherwise.  When the status code before
    transformation would have been different, the 214 Transformation
    Applied warn-code (Section 3.6 of [Part6]) is appropriate.

    Caches MAY use a heuristic (see Section 2.3.1.1 of [Part6]) to
    determine freshness for 203 responses.

...and the Changes section would state:

    Broadened the definition of 203 (Non-Authoritative Information) to
    include cases of payload transformations as well.  (Section 8.2.4)

Best regards, Julian
