I first saw .sdl used by a D package. I liked it as an alternative to XML where there is a hierarchy, beginning and end tags (sdl uses {}) and multiple children at the same level, but at this point, the only reason why I decided to use it in my D projects was because the API to parse it is more convenient than using dxml imo.
