A note was passed along to me about a new project that's been created to help make the generation of ODF-XSLT documents simpler - the ODF-XSLT Project from Lone Wolves.
Lone Wolves is happy to announce the ODF-XSLT project [1]. The ODF-XSLT Document Generator is a library written in PHP 5 that brings the full power of XSLT to your OpenDocument files. It enables you to use ODF files as if they were plain XSLT templates. It also includes a few extra parsing options that allow you to edit the XSLT parts of these ODF from within your favourite office suite.
The tool was developed by Tribal Internet Marketing and is being released under a GNU Public license, version 3. You can get more information about the project from its homepage including things like downloads, the manual and their subversion repository address.
