We apply the fallback disc model, which explains the period clustering and other properties of AXP/SGRs, to the six XDINswithmeasuredperiodsandperiodderivatives.PresentpropertiesofXDINsareobtained in evolutionary scenarios with surface dipole magnetic fields B0 ∼ 10 12 G. The XDINs have gone through an accretion epoch with rapid spin-down earlier, and have…
