note = {It is shown that the numbers of off-diagonal solutions to the Uq(X(r)N ) Bethe
equation at q = 0 coincide with the coefficients in the recently introduced canonical power
series solution of the Q-system. Conjecturally the canonical solutions are characters of
the KR (Kirillov-Reshetikhin) modules. This implies that the numbers of off-diagonal solutions agree with the weight multiplicities, which is interpreted as a formal completeness of the Uq(X(r)N ) Bethe ansatz at q = 0.},
