I've finished the review of the localization I made for the Open Language Editor. This editor was the one I have used a long time ago (may be 1.1.3) for OOo localization dealing at this time with .xliff files. It's able to read several file format. The fun part was that to localize it you need to run it ;-)

Thanks to Simon and Mechtilde from the German community to take care of it.
