Good point, I thought about it too. My point was to use `"0"` or `"1"` in case you receive information from outside. When one passes `true` to an request you need to map it in your application to pass the boolean to the method. Then the method that was called need to map the boolean back to a string to create the querystring. At the end for me it is a philosophic question what to use. You decide. :blush:
