In a d-wave superconductor with elastic impurity scattering, not all theavailable optical spectral weight goes into the condensate at zero temperature,and this leads to residual absorption. We find that for a range of impurityparameters in the intermediate coupling regime between Born (weak) and unitary(strong) limit, significant oscillator strength remains which exhibits a cusplike behavior of the real part of the optical conductivity with upwardcurvature as a function of frequency, as well as a quasilinear temperaturedependence of the superfluid density. The calculations offer an explanation ofrecent data on ortho-II YBa$_2$Cu$_3$O$_{6.5}$ which has been consideredanomalous.Comment: Accepted for publication by Phys. Rev. B 7 Pages and 4 Figure
