Tony,

R12 can use the start parameter or the ordering, so I think this is
covered. It's the concrete usecase behind the late R11 which I was
asking for. Such a usecase could be a good rationale for mandating that
the receiver understand the start parameter (and not mandating that the
SOAP part is the first one).

Best regards,

                   Jacek Kopecky
