GXA

The Global XML Web Services Architecture (GXA) was an announcement[1] by Microsoft in 2002 of several proposals for extensions to SOAP. Some of the components of GXA were developed into standards in combination with other companies, including IBM. Others were specific to Microsoft and have been superseded. Microsoft released a reference implementation of a part of GXA as Web Services Enhancements 1.0 SP1 for Microsoft .NET (WSE).
