Re: non-ebXML links - T2
(I may be repeating myself but just in case...)
OK. That makes sense but the spec. doesn't say it and should say it.
One thing has to be clarified. There is a difference between "transport
layer" and "external to the MSH". "External to the MSH" could be in a
higher or lower layer. The IBM MQSeries example that people keep
mentioning is a higher layer and would not usually be considered
"transport". In the MS spec, "transport" is either SMTP or HTTP, neither
of which are reliable.
I would agree to the meaning of "external to the MSH", with suitable
explanation, but would prefer that the value of the attribute be changed
from "Transport" to something broader like "other", which would cover both
HTTPR (when standardized) and reliability in a higher layer.
Regards,
Marty

All,
The value "Transport" means that the reliable semantics of
OnceAndOnlyOnce are provided for by the transport layer, not the
MSH layer of software.
It means that the enforcement of the deliverySemantics are
provided for external to the MSH such that the ebXML RM
protocol artifacts are not used/necessary.
Cheers,
Chris
