Abstract = {{Recently, charge density wave (CDW) order in the CuO2 planes of
   underdoped YBa2Cu3O6+delta was detected using resonant soft x-ray
   scattering. An important question remains: is the chain layer
   responsible for this charge ordering? Here, we explore the energy and
   polarization dependence of the resonant scattering intensity in a
   detwinned sample of YBa2Cu3O6.75 with ortho-III oxygen ordering in the
   chain layer. We show that the ortho-III CDW order in the chains is
   distinct from the CDWorder in the planes. The ortho-III structure gives
   rise to a commensurate superlattice reflection at Q = {[}0.33 0 L] whose
   energy and polarization dependence agrees with expectations for oxygen
   ordering and a spatial modulation of the Cu valence in the chains.
   Incommensurate peaks at {[}0.30 0 L] and {[}0 0.30 L] from the CDW order
   in the planes are shown to be distinct in Q as well as their
   temperature, energy, and polarization dependence, and are thus unrelated
   to the structure of the chain layer. Moreover, the energy dependence of
   the CDW order in the planes is shown to result from a spatial modulation
   of energies of the Cu 2p to 3d(x2-y2) transition, similar to
   stripe-ordered 214 cuprates.}},
