I'm not sure if we are talking at cross purposes here. So I'll give an example -
My logical message is -
<AddNumbers>
<First>10</First>
<Second>20</Second>
</AddNumbers>
I want to call a Dispatch and pass in the XML as above.
If I set the binding in my wsdl file to be pure XML, I expect to see the XML
above passed over the transport.
If I changed the binding to SOAP, I would expect it to look like -
<SOAP-ENV:Envelope>
<SOAP-ENV:Body>
<AddNumbers>
<First>10</First>
<Second>20</Second>
</AddNumbers>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
If I changed the binding to be Corba it would be in a binary coded format
(not shown)
My understanding of the interceptor chain is as follows (and maybe I have this
wrong, which is where my mis-understanding lies) -
Client side
===========
A - I call a function of my port using java objects
B - It gets converted into XML (JAXB)
C - XML goes through binding layer to format the message
D - The transport sends the formatted message
Server Side
===========
E - Transport receives the message
F - binding layer decodes message into XML logical message
G - XML is converted into java objects (JAXB)
H - I have my message as a java object
I want this process to start at C and end after F so that I pass a logical XML
message and receive my reply as a logical XML message even though the
binding/transport may not have used XML for the communication. I'm doing this
at the moment by adding my own JAXB calls before A and after H.

It only skip mashall/unmashall for binding layer, but can not skip the
transport layer, anyway, you need deliver message to remote process

SOAP payload is not compulsory here, you can use any payload you like.
Thanks very much
