Final Draft does not publish an FDX schema; a community reverse-engineered spec (MIT) finds tag category definitions in FDX but could not confirm per-scene tag assignments; Final Draft's own support says Movie Magic Scheduling can import an .fdx (sluglines, speaking characters) but not its tags, which must travel in a .sex export whose format no inspected page documents.
