This Service is implemented by Discovery Servers.
This Service allows a Server to register its DiscoveryUrls and capabilities with a Discovery Server. It extends the registration information from RegisterServer with information necessary for FindServersOnNetwork. This Service will be called by a Server or a separate configuration utility. Clients will not use this Service.
Servers that support RegisterServer2 shall try to register with the Discovery Server using this Service and shall fall back to RegisterServer if RegisterServer2 fails with the status Bad_ServiceUnsupported.
A Discovery Server that implements this Service needs to assign unique record ids each time this Service is called. See 5.4.3 for more details.
This Service can only be invoked via SecureChannels that support Client authentication (i.e. HTTPS cannot be used to call this Service).
