The B717 FCOM & AFM both define icing conditions as TAT < 6 and visible moisture, and both documents require engine anti icing on in such conditions. Such definition doesn't give one much leeway.
Back in the good 'ole days, the BAe 146 icing definition was worse, and advice was that BAe would sue the next person who experienced an icing related engine roll back.
