properties that may or may not be valid. If this is intentional and desired, this should still be captured somehow, e.g. in the bindings documentation or in the code with a comment, no?
Yes, I agree with you on this, I should document this in bindings!
thanks for the explanations, it'd be useful indeed to document what this magic 0xFF value means.
