You create an XML Web service project that consists of three services named BronzeService, SilverService, and GoldService. All three services are located in the same virtual directory on a production computer. When customers subscribe to your service, they select only one of the three available services.
A new customer subscribes to SilverService. You need to create a discovery document that enables this customer to use only SilverService.
Which discovery document should you create?
A.
