but of course that means you are in the position that the (presumed)
attacker is in under the proposed attack - and he will have the same
objections to you defining the document as you do.
For that matter - many people are in the position of having to sign
documents without alteration. Contract negotiation is a wonderful
theory, but too many people get basically a "take it or leave it"
choice.
