OpenOffice documents may now have one root
This is good news.
The present format, with five or more XML files zipped together, is really--like Microsoft Office--only suitable for human editing. The single root XML format will make XSLT based processing possible, combining human editing with automated workflows. One XSLT may extract chapter headers form a text document, another create a spreadsheet from a naked data XML. The sky's the limit. For the first time, OpenOffice has something MS Office has not. And will never get - Microsoft won't ever use an open format for Office.
