No.. but a SOAP "infoset" is the canonical message format we use.. what 
this means is that our internal message payload is represented as a SOAP 
"infoset" - Note, this is NOT a SOAP envelope serialization of the 
payload as XML - but just an internal representation of the tree like 
model of attributes and elements in memory. A SOAP infoset can carry, 
SOAP, POX, Plain Text and Binary payloads without any overhead. For 
example, if you are dealing with binary content, it would be kept in a 
DataHandler, and the SOAP infoset will refer directly to that. This 
allows each mediator to interact with any message as a SOAP message - 
but access the binary or text payload as necessary, or the more common 
SOAP envelope or a POX XML payload etc
