Subject: Re: [wsbpel] Issue - 152 - New Proposal to Vote


    I'm not sure if you've seen the main argument for having the 
reference-scheme attribute (optional or not). Suppose we had a service 
reference like the following:

       <wsdl:port name="MyNotificationPort" ...

The addressing schema to apply is less than clear. If my BPEL run-time 
is clever, it might guess that WS-Message Delivery is implied, but it 
will be at a loss to figure out which version of WS-MD to use. Also, it 
is reasonable to assume that other specifications, trodding the same 
ground as WS-MD, will take a similar approach, using wsdl 1.1 ports and 
wsdl 2.0 endpoints.

    It is for these cases, where the QName of the element enclosed by 
the <ServiceRefType> is not sufficient to resolve the endpoint reference 
scheme in use, that the reference-scheme attribute is needed.

    If we adopt the proposed resolution to the issue 152 (below), how 
are we to address the above problem?

Best regards,
