      This is the XML Schema for endpoint descriptions used by
      the Remote Service Admin Specification. Endpoint descriptions
      are used to describe remote services to a client in cases
      where a real live Discovery system isn't used. An extender,
      such as a local Discovery Service can look for service
      descriptions in installed bundles and inform the Topology
      Manager of these remote services. The Topology Manager can then
      instruct the Remote Service Admin to create client proxies for
      these services.
