\ indicate the value is in transition - does not have the new value yet

server: handle synchronous and asynchronous value updates and initialization it needs to handle these case: not initialized and not in transation: initialze and commit the value not initialized and in transation: if dependent on external settings initialize a temporary and compare it with the new value and update the external setting if required make sure to commit the new value so listeners get notified either synchronously or asynchronously by external notification initialized and in transition: update external settings if any and make sure to commit the new value so listeners get notified either synchronously or asynchronousl by external notification

server will not be called with this state: initialized and not in transation
