Seems like that there are actually a couple things one would want:

1. In cases where an underlying protocol does not support reliable
messaging, then a layer on top, such as soap header blocks, would provide
reliable messaging.
2. Use of Web Service abstract feature to support mapping a "reliability"
feature to various soap features, protocols, message exchange patterns.

Cheers,
Dave
