220.127.116.11.1.4 Registering a Dynamic Endpoint with Endpoint Mapper
If a server is using a dynamic endpoint, it SHOULD register the list of endpoints that are associated with the given interface UUID/version and object UUID with the local instance of the endpoint mapper. This is done in an implementation-specific way. These extensions do not allow registering on nonlocal instances of the endpoint mapper.
If a server uses a well-known endpoint or uses a mechanism specified outside these extensions for discovery of dynamic endpoint, it can skip this step.
