Doug,

In an earlier version of WS-Eventing Appendix A there was a long part 
http://www.w3.org/TR/2010/WD-ws-eventing-20100330/#id35822170
After removing this part I thought that the EventDescriptions should not 
appear anymore in MetadataSections.

Maybe it is possible in WS-Event-Descriptions Section 4.1.1 to express 
more clearly, that the EventSource Policy and the MetadataSection are 
two different things, otherwise the solution with the MetadataSection 
might get lost when skimming over the spec.

So what about the NotificationWSDLs? From the current editor's 
WS-Eventing spec, it is not clear for me that the NotificationWSDL is 
retrievable via a MetadataSection. Especially since in section A.2.1 
http://www.w3.org/TR/2010/WD-ws-eventing-20100330/#id35822333 the gray 
box and Section A.3 was removed.

Regards,
Stephan
