We present a measurement of the total branching fraction of theflavor-changing neutral-current process B->Xsl+l-, along with partial branchingfractions in bins of dilepton and hadronic system (Xs) mass, using a sample of471x10^6 Upsilon(4S)->BBbar events recorded with the BaBar detector at thePEP-II e+e- collider. B mesons are reconstructed by combining a dilepton pair,either e+e- or mu+mu-, with 10 different Xs final states containing exactly onecharged or neutral kaon, two or fewer charged pions, and at most one pi0. Usinga sum over these exclusive modes as the basis for extrapolation to the fullyinclusive rate, we measure a lepton-flavor-averaged inclusive branchingfraction BF(B->Xsl+l-) = (6.73 +0.70-0.64[stat] +0.34-0.25[exp syst] +/-0.50[model syst])x10^-6 for m(l+l-)^2>0.1 GeV^2/c^4. Restricting our analysisexclusively to final states from which a decaying B meson's flavor can beinferred, we additionally report measurements of the direct CP asymmetry ACP inbins of dilepton mass; over the full dilepton mass range, we find ACP=0.04 +/-0.11 +/- 0.01$ for a lepton-flavor-averaged sample.
