XTS update

It's nice to see that there are other commercial and OSS vendors looking to provide new implementations of WS-TX. However, it is worth stressing the points I made earlier: not only was XTS the world's first Web Services transactions implementation, but it is the only open source implementation that has been tested for interoperability with IBM, Microsoft and others. So if interoperability with heterogeneous implementations is important to you, come talk to us.
