I am a little late in pointing this out but we are half-way through the (hopefully final) public review of the WS-Notification family of specs (WS-BaseNotification, WS-BrokeredNotification and WS-Topics). You have one more week to review the specs and send your comments. Many of the changes in WS-BaseNotification and WS-BrokeredNotification relate to lifecycle management and how these specs relate to WS-ResourceLifetime. There is only one change to WS-Topics but I think it is a pretty major improvement. It cleans up how extension topics appear in a TopicSet document. All the links and information on how to comment are in this announcement.
