No, that doesn't follow. If the information is out-of-band, then it's not
discernable and is not a difference in the document, it's a difference in
the way it is used.

I think you're completely off target here. It all depends what the document
is for. If you're trying to say that a document containing an instruction to
move $1000 from account A to account B is bad because it's active and
procedural, then I would say that's nonsense. Or at any rate, I would say
"why is it bad?".
