I suppose that could be one way to do it.
I'd also recommend to you page 7 of the Mines Action Canada written submission, where it draws upon the implementing legislation for the Ottawa treaty. That's one option. In the Harvard submission on page 10, there is some suggested language as well that's an alternative. It talks about “mere participation”. Those are some options to consider. The Canadian Red Cross in its submission on page 4 also has some very specific suggestions about clause 11.
