// XD convection_ale convection_deriv ALE NO_BRACE Keyword for ALE-specific convection in VEF/VDF discretizations. At
// XD_CONT runtime, TRUST's Discretisation_base maps `ALE` to the Op_Conv_ALE_<discr> operator (e.g. Op_Conv_ALE_VEF
// XD_CONT here); the inner readOn delegates to Op_Conv_VEF_Face::readOn, which accepts the same scheme parameters as
// XD_CONT `convection_generic`. NL2 Examples: NL2 convection { ALE amont }NL2 convection { ALE muscl vanleer 2 }
// XD attr type chaine(into=["amont","muscl","centre"]) type REQ type of scheme
// XD attr limiteur chaine(into=["minmod","vanleer","vanalbada","chakravarthy","superbee"]) limiteur OPT type of

// XD attr ordre entier(into=[1,2,3]) ordre OPT order of accuracy, for muscl
