### Description

A lattice calculation of inclusive decay structure functions for $B¥to X_c¥ell¥nu$ is compared with the corresponding estimates based on the heavy quark expansion. Both methods are applicable in the region away from the resonances/cuts due to final charmed states, and one can test the theoretical methods employed on both sides.
