@matigo I don't think making it compatible is your issue. If you output well-formed XML, the importer should be able to use that. It's an issue for the importer, not the exporter.
Now, the folks to that do make it easier to import from different platforms are doing so because they want to gain clients. Not your worry if people want to leave 10C. Their new platform will make it super easy, right?
