Do not add properties to bindings to "pass the test". That's not the goal of bindings. Add there properties because they make sense... Anyway, you did not answer my question at all. So one by one - address them: 1. As you can easily check, there is no such property in any devices. Explanation: do you see it anywhere in existing bindings? 2. I don't understand why do you need it in the first place. Explanation: your binding suggest this is not needed. If you think otherwise, you need to provide rationale. Best regards, Krzysztof
