Currently, validation (triggered by save() or saveAndReload) always tests against the latest version even if SetODFDefaultVersion() has set the version to SvtSaveOptions::ODFVER_013, for example. If the latest version has a mandatory attribute or element that does not exist in the previous version, the validation will fail. That is currently the case for the new attributes draw:handle-position-x, draw:handle-position-y, draw:handle-polar-pole-x and draw:handle-polar-pole-y. So the request is to extend validation so, that the actual ODF version at time of saving is considered.
