Does it implement a global registry for searching for kinds of services, the way uddi works? Does it allow you to publish your service to a central directory the way uddi does? I appreciate your answer and my knowledge on soap/xml is increasing. Just out of curiousity what would be an example of where rpc/xml would not be able to do something requiring soap/xml?
