fly with instructor for solo hours
What part of "solo" do you not understand? JAR-FCL is 100% clear on this. You have to be the only person on board if your flight is to be classified as "solo". And the take-offs and landings for the NQ have to be done solo.
We can discuss whether this is sensible, safe and reasonable but at the end of the day that is what is written in JAR-FCL, and made into law in most countries.
grant exemptions from those that do not.
Okay, I guess I should have made my point clearer. You cannot "grant exemption" from something that's not a regulation. So a country cannot grant an exemption from JAR-FCL. They can only choose not to implement bits of JAR-FCL into law, or implement something slightly different (or even wildly different) into law. And only once it's in the law books they can grant an exemption. From the law, not from JAR-FCL.
But I agree that it's all semantics.
