Some Questions: 1. Do we have a business need to have multiple service catalogs? - 2. Do we have a need to have a service descriptor in a given catalog multiple times for different time periods? - 3. How do we handle moving a descriptor from a test catalog to a production catalog? - 4. What is the attachment class? Presently, SDC stores the descriptor directly in the catalog. I don't think SDC uses the SID Characteristic patern. The value of a given ServiceCharacteristic
