Texture resolution

Does it mean to have different xml files for different resolutions?
Then why unwrapMinTexResolution and unwrapMaxTexResolution are introduced if they don’t take any effect?
It is expected that when mentioned (min and max) keys are set, then -unwrap should use those values, but actually it does not. Why? Is it a bug?

And what would be the result of unwrapping things in 1024, but exporting with texture maximal side set to 8192 ?
