F&P/MTOM Alternate proposal







Per my action item, here is an alternative proposal for MTOM support 
within WSDL2.0.
This is a translation of the current MTOM support through an extension 
element.
Regards,
    Youenn
-----------------------------
The proposal is the following:

Add a new WSDL2.0/MTOM extension within section 5 (soap binding) of the 
WSDL20 adjunct specification, along the following lines.

//// WSDL Component Relationship /////
The WSDL2.0/MTOM extension adds the following property to the WSDL2.0 
Endpoint, Binding, Binding Operation, Binding Fault, Binding Message 
Reference and Binding Fault Reference components:
   - {optimizedMimeSerialization} OPTIONAL. Its type is xs:token. When 
present and equal to "required",  it indicates that MTOM  must be 
engaged. When present and equal to "optional", it indicates that MTOM 
may be engaged. When not present, no assertion is made about the use of 
MTOM.

The requiredness/availability of the MTOM engagement is defined by the 
closest present property, where closeness is defined by whether it is at 
the Endpoint component level, the Binding Message Reference component or 
Binding Fault Reference component level, the Binding Operation level, 
the Binding Fault Reference level, or the Binding component level, 
respectively.


//// XML Representation ////
The XML representation for the WSDL2.0/MTOM  extension is an element 
information item as follow:
   <wsmtom:OptimizedMimeSerialization wsdl:required="true|false"?
 
xmlns:wsmtom="http://www.w3.org/2004/08/soap/features/http-optimization"/>
This is an empty global element that allows any namespaced attribute 
(especially the wsdl:required attribute).

//// Mapping ////
The {optimizedMimeSerialization} property is present when a 
wsmtom:OptimizedMimeSerialization element is present.
Its value is "required" if the wsdl:required attribute is present and 
equals to "true". Otherwise its value is "optional".
