SOAP 1.1 Binding for MTOM 1.0 is a specification that describes how to use the SOAP Message Transmission Optimization Mechanism (MTOM) and XML-binary Optimized Packaging (XOP) specifications with SOAP 1.1.
This specification defines the minimum changes required to enable MTOM and XOP to be used interoperably with SOAP 1.1 and to reuse the SOAP 1.2 MTOM/XOP implementation.
