Jiri Pachman has written fo2wordml, a stylesheet to convert XSL-FO to Microsoft's WordprocessingML format. (This is the second such tool for that I've seen in the last couple of weeks. I'm amazed this is even possible.)
Sébastien Cramatte has posted xslt2Xforms 0.7, an XSLT stylesheet that adds W3C XForms support to a web browser using XHTML, Javascript and CSS. This release only works in Mozilla.
