proposed amendment, simplified version:

<TEXT>
Normative:
Conflicting and/or duplicate DNT headers MUST be treated by the server 
as a single DNT header on the principle of exclusive OR (hereafter: XOR) 
of the DNT value. The server MAY alert the user about possible user 
agent misconfiguration.

Non normative:
Exclusive OR is a simple way to state "one or the other(s) but not 
both(or all)".
</TEXT>
