I have not seen anything that could come close to the robustness and flexibility XML has to offer. When being used for configuration XML seems to be the superior choice. People tend to give XML a bad name in RPC usage for being verbose. But, for config it’s perfect for me. There are tons of IDEs supporting XML (syntax highlight & collapsing brackets, etc...). XML schema is also great to ensure the config is conforming. I keep thinking we are trying to reinvent a worse wheel here.
