Future Extensions and Forward Compatibility
For QDocs using the 1.0 standard, the content of the QDoc envelope—while mostly SOAP compliant—is entirely QAD defined with no reference to external industry standards or specifications outside of SOAP. Qdocs using the 1.1 standard follow the Web Service Addressing (WSA) standard. As XML- and SOAP-based messaging standards mature, the QDoc envelope will evolve to address authentication, privacy, reliability, and work flow requirements among others.
