    I had a look at the Wikipedia page, and my conjecture about how these things work was correct. I also thought about a proof involving vectors exactly as you describe. I still have no clue what a p-invariant is, though - the Wikipedia page doesn't even mention it. Back to Google U . . .

    OK, I found a reference that seems to explain the importance of p-invariants. Working through it . . .

    This link gives you the final piece. Theorem 2.33. What that book calls s-invariants, I call p-invariants. M0 is what I call the initial marking, and M is the target marking (0,0,1,1,0,0,0), and I is the invariant. Prove that the marking M fails the necessary condition.
