I think it is more akin to an agreement to make an agreement. Which I believe, would normally be unenforceable due to lack of certainty.
So the "Treaty" isn't really a treaty, it's a Gentleman's agreement to have a Treaty? Then none of it is enforcable in law, because the bit you dislike is not specified to your liking and is rather vague?
Anymore lame excuses for how an agreement which specifies that something can be done, but does not specify how, when or why it can be done, means it can't be done?
It's amazing how the resident self-appointed legal expert says read the 'Treaty', but when the treaty is not worded to his liking, he says it's not really what it claims to be.
So if the law doesn't specifically say I can do something, it means I can't do it.
That's a nuisance because I was going to covert my old caravan into a boat trailer, but because the law doesn't cover that possibility, it means I can't.
I'd better tell everyone else that had a similar idea. I'd better tell the suppliers of trailer parts, as well, that their market has just been destroyed because the law does not specifically allow the construction of DIY trailers.
And as for self-build houses, I'll have to put that idea on the back-burner as well.
