The recently observed Ds(2317) meson is explained as a scalar c+anti-s system
which appears as a bound state pole, below threshold, in the DK scattering
amplitude. The standard c+anti-s charmed scalar D_{s0} is found at about 2.9
GeV, with a width of some 150 MeV.
For the scattering length of DK in S wave we predict 5+-1 1/GeV.
