Description	When reduced from 10 to 10 -?? dimensions tree-level string theory exhibits an ???(??,??) symmetry. This symmetry, which is closely related to ?? duality, appears only after certain field redefinitions. We find a simple form for a subset of these redefinitions at order ??'3 and show that they cannot be lifted to ten dimensions. This is inconsistent with “manifestly ?? duality invariant” approaches such as generalized geometry (in the uncompactified setting). Such formulations therefore seem not to be the correct language to describe string theory.
