[NEW ISSUE] WS-Eventing Notifications violates WS-I BP

WS-Eventing proposes that the event source define some output-only 
operations for the events it will send, as shown in the following example 
from the spec: 
<wsdl:portType name="Warnings" wse:EventSource="true" > 
  <wsdl:operation name="WindOp" > 
    <wsdl:output message="tns:WindMsg" /> 
  </wsdl:operation> 
</wsdl:portType> 

WS-I Basic Profile R2303 says the following: 
4.5.2 Allowed Operations 
Solicit-Response and Notification operations are not well defined by WSDL 
1.1; furthermore, WSDL 1.1 does not define bindings for them. 

R2303 A DESCRIPTION MUST NOT use Solicit-Response and Notification type 
operations in a wsdl:portType definition. 

Proposal:
Replace this with some WS-Policy that will allow an event source to 
advertise which events will can generate.

thanks
