Thanks for declaring where to find test files (I'll check them out), but I think /doc should also include some general description of the format. You put the .ksy spec in the firmware directory, which suggests that the format is somehow firmware-related, but anything beyond that is left to the reader to guess. I guess it's a firmware update format of IP cameras of a certain brand Fullhan? At least one or two sentences would go a long way for someone not knowing the purpose of the format or perhaps trying to find a .ksy spec for it via certain keywords.
