Its not a matter of taste to me but rather a matter of principle;
the abstraction should support thinking about the data involved and
if there's a need for headers just insert them using soap:header.

See that's the wrong place to start IMO- applications don't start by
thinking about two pieces of data and where they come from the SOAP
envelope. If the app has two pieces of data, then the solution is
to send both as payload. If in sending that it needs to indicate 
some additional headers to be sent, then use soap:header to do it.

If the 2nd piece of data is indeed a SOAP header, then put a soap:header
element in the binding to insert that header and put only the first 
guy as the payload.
