If your publisher requires word documents (or _any_ word processor format), you need to find a better publisher. I can understand if they prefer word for the text-copy, which is then pulled into a typesetting app. But to use that as the pre-press format is a terrible workflow. This isn't a limitation of LibreOffice, it's a limitation of not being competent in pre-press typesetting and publishing software.
