WS-Notification is part of the WS-ResourceFramework. Mark Potts, distinguished technologist at HP, has made comments about WS-Notification in this article. (Thanks to my boss, Paul Watson, for pointing this out).
I know Mark from my HP days. He is a very nice and clever guy. I am meeting him for dinner in few days. I am looking forward to talking to him about WS-ResourceFramework and, of course, catch up.
