Produced by the XML Protocol Working Group, SOAP Version 1.2 is a lightweight protocol for exchanging structured information in a decentralized, distributed environment such as the Web.

• Using an XML Schema datatype, XML-binary Optimized Packaging (XOP) allows efficient serialization of XML element content.
