JsonML (JSON Markup Language). An almost non-lossy serialization format for sending XML as JSON (plain text in between elements is ignored). Uses the (element-name, attribute-dictionary, list-of-children) tuple format, which sadly means many common cases end up taking more bytes than the original XML. Still an improvement on serializations that behave differently when a list of children has only one item in it.
