 That's a rather broad exception.

I suspect Fateman may have been referring to some particularly weird
functions of measure zero, that is, whose integrals are zero over any
finite interval, yet which also contain an infinite number of nonzero
values over any finite interval, yet no value is negative. [We had to
construct some in my sophomore topology seminar (long, long ago)...]
