TUSCANY-3093 - changes required to pass the callback endpoint URI in the from field of the web service WSA header "from" element. Includes associated changes to do something useful with this URI. There are changes here I had to make that push on the meaning of the InterfaceContract in endpoints and endpoint references. Needs further discussion.
