We're working with LibreOffice, but MS also supports OpenDocument. The quality of the XML produced by these programs is extremely poor. LibreOffice, for example, changes the name of every (or nearly every) automatic style every time you save, which makes it very hard to use the diffs. Also ODS doesn't stride formula references when you repeat rows, which baffles me. Nonetheless, by simplifying the FODS files to use a subset of the format, the diffs are looking okay now. I created a wee little canonical string representation of the style parameters I want to use, and putting that string in the style:name attribute when I clean up the document.
