According to the Bean FAQ page:
Saving a document with images using .rtf or .doc format will convert the images into a .jpg, so if fidelity and speed are required, use .rtfd format instead. On the other hand, if compatibility with a non-Apple computer is required, use the .rtf or .doc formats, as they are easily read by both Word and LibreOffice. Non-image attachments (e.g., .mp4 files) must be saved using the .rtfd or .bean formats. So it sounds as if there is a menu option somewhere to export or convert as a Word docx.
If I misunderstood what you meant by "xword", then never mind.
