[Bug 8274] New: interoperability of non-addressable event sinks

http://www.w3.org/Bugs/Public/show_bug.cgi?id=8274

           Summary: interoperability of non-addressable event sinks
           Product: WS-Resource Access
           Version: PR
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Eventing
        AssignedTo: public-ws-resource-access-notifications@w3.org
        ReportedBy: gilbert.pilz@oracle.com
         QAContact: public-ws-resource-access-notifications@w3.org


Section 2.2 "Delivery" contains the following paragraph:

"When the wse:NotifyTo element is used within the Delivery element it specifies
the endpoint to which notifications are sent. For delivery to addressable
endpoints this is sufficient. However, for non-addressable endpoints some
additional mechanisms are needed. A subscription manager MAY choose to support
mechanisms, such as the [WS-MakeConnection] specification, to enable delivery
of notifications to non-addressable endpoints. See the [WS-MakeConnection]
specification for more information, and an example, of how this would work."

The "MAY choose to support" clause in the above means that the set of event
source implementations that support non-addressable sinks will be fractured
into those that support WS-MakeConnection and those that support some other
polling mechanism. The has obvious impacts on interoperability.

Proposal: rephrase the above to

"When the wse:NotifyTo element is used within the Delivery element it specifies
the endpoint to which notifications are sent. For delivery to addressable
endpoints this is sufficient. However, for non-addressable endpoints some
additional mechanisms are needed. Event sources and subscription managers that
support non-addressable event sinks MUST support the [WS-MakeConnection]
specification."
