ebXML CPPA Versions 1.0 and 2.0 are complete. Version 2.0 is an approved OASIS Standard. An ebXML CPPA Negotiation specification is currently under development. A maintenance 2.1 version will fix several minor errors that have been detected and resolved and add enhanced extensibility points to the schema. Plans for a version 3.x will emerge as other ebXML specifications (ebXML Messaging and ebXML Business Process) move forward.
