UPDMRTF — Need for ServiceInterfaces to be represented as an instance to capture specific ServiceAttributes

ActualServiceInterface:
This would be an element that is the equivalent of the MODAF element ServiceLevel and would contain slots and instance values for the properties that have been defined for ServiceInterface. There would be a need to provide a tagged value to any usage of the ServiceInterface as a port either on a NodeRole or ResourceRole where the actual service interface would be indicated that is to be viewed as a requirement for this particular context. For the port used on the ResourceRole there would also be a need to indicate how many instances of the actualServiceInterface that the ResourceRole would need to accomodate, at least if a complete mapping to between MODAF and UPDM is to be achieved. (All of this actually exists already as part of the MODAF model that UPDM is supposed to implement).
