You mean for translations? Well, this is still a very very early version of the final release of the game. So, as I know, there could be a more easy way to translate things, later in higher versions. For now, I don't know another way than using the actual files and translating all the texts within the data-files themselves. But I only know the tiny bit I already learned. Maybe you should ask this in your own thread in the forum.
Beside of this, I don't think, it's so hard to create a little program, reading all the xml-files, getting the texts, creating a translation table with and for that own program and switching the texts with this translation table in the files in the end.
