OARIS21 — register_interest_type is missing service information

The OARIS 2.0 specification says registration includes information on:

• The service for which the actor wants to register / deregister his interest
• The information within the service for which the actor wants to register / deregister his interest
• The intended (direct or indirect) recipient(s) of the information provided by the subsystem
• Any parameters of the provision needed such as Quality of Service parameters

But according to the IDL, register_interest_type contains a sequence of interest_type, which contains only the registration type (REGISTER or DEREGISTER), the recipent, and quality of service. The message has no way to specify a service or information within a service; the first two bullet points in the requirements above.
