Greg>Having numerous formats derived from a single master is a long-time goal. We've had some success with RST and TEI, and I've encouraged new projects to consider RST. There are still some limitations, though... Greg>On the many, many words on gutvol-d recently about poor results with auto-conversion from HTML to other formats (epub and mobi, among others): this is often due to choices that producers make about using HTML to impact layout, rather than just structure. Enough said. This combination of paragraphs doesn't make sense. I recently posted in this forum an analysis, based on a request from this forum, that indicated that RST in practice *is not* working as a "single master." To whit the EPUB and MOBI being generated from RST is not particularly successful, possibly no more so than the DP "HTML" efforts.
