Yes, the severity level is stored as an int, and therefore the attr
formatter uses operator<< for ints. Right now you can either define your
own formatter that will accept an int and transform it into a string, or
develop your own attribute and logger to store the level as an enum
(then the attr formatter should be used with explicitly specified enum

I haven't decided yet how to solve this problem best in the library.
