JSX translates between Java objects and XML. It does this by subclassing Java's standard "Serialization API", so it is transparent to switch between binary and XML formats. Literally all objects are handled, including classes that customize their serialization (eg Collections), for evolution and versioning. Unique in data binding, JSX solves the problems of no-arg constructors, final fields, and multi-dimensional arrays, and so makes XML persistence and communication easy.
