Fabio Giannetti of HP has created WH2FO, a Java application to transform from Word 2000 HTML output to XSL Formatting Objects.

The use of an XSL-FO processor, such as Apache XML Project's FOP, can then take your Word document into PDF. WH2FO supports a reasonable set of markup features ranging over pagination, layout, text styles, lists and images.

WH2FO can be downloaded from HP Labs' web site.
