n|i If set to a nonnegative integer value, input values greater or equal to this value are forbidden and will cause an error log. If set to nil, any integer is accepted as input. A restriction makes it possible to use the object for widgets that only support a limited range.
target
Optional attribute;
read/write access; type:
o|[os]|n Object to which numeric state is propagated. The current state is sent to the target object via the uint64_state interface whenever it is changed to a new value. This can either happen by input from another object via the uint64_state interface, or by user input from the system panel frontend.
