CodeSynthesis XSD/e is a validating XML parser/serializer and C++ XML Data Binding generator for Mobile and Embedded systems. It is developed by Code Synthesis and dual-licensed under the GNU GPL and a proprietary license. Given an XML instance specification (XML Schema), XSD/e can produce three kinds of C++ mappings: Embedded C++/Parser for event-driven XML parsing, Embedded C++/Serializer for event-driven XML serialization, and Embedded C++/Hybrid which provides a light-weight, in-memory object model on top of the other two mappings.
