They might not be "errors" per se, but just incompatibilities. For example, if any of your XML files have capital letters, it won't work on Linux. Windows doesn't differentiate between capital and lower-case letters, while Linux does, so if Linux is looking for a unit called "unit_1", and all you have it "Unit_1", it won't work. That's my understanding of things, anyway, but the gist is "don't use capital letters".
