RE: [wsrm] reliable WSDL request-response MEP

Title: RE: [wsrm] reliable WSDL request-response MEP

Variant 1 ( guaranteed deliv on both request and response)

and Variant 2 (guaranteed deliv on request, not response)

do not seem to pose problem,

unlike Variant 3 (guaranteed deliv on response, not on request).

I can't think of any use case for Variant 3 either, but someone may have one?

Maybe along differences in capabilities (e.g. sending to a WS from a small device...)

Beyond this case study, it appears we may need to write down some rules telling 

what reliability features can/cannot be used with what application MEPs and transport bindings.

Thanks for the good work to lay out the issues and possible solutions.

I really wonder what the use cases are for variants 2 and 3.  If we can 

simplify the protocol

by only supporting variant 1 (reliable request with reliable response) 

we will get out of the gate

sooner and meet the major use case for reliable request/response.
