Link: https://issues.oasis-open.org/browse/OFFICE-4110 ODF 1.4 replaces the attributes draw:handle-polar and draw:handle-position with the new attributes draw:handle-position-x draw:handle-position-y, draw:handle-polar-pole-x, draw:handle-polar-pole-y, draw:handle-polar-radius, and draw:handle-polar-angle. Task is to write these new attributes in addition to the old attributes. The old attributes are deprecated but may be written, so we keep them for backward compatibility. The import from ODF 1.4 must use the new attributes and ignore the old ones. Only ODF import and export is affected.
