Question: In an MBMS (Multimedia Broadcast/Multicast Service) aggregate service announcement document, what is the recommended practice for including referenced metadata fragments for each MBMS user service description?
Option 1: Include only a subset of referenced metadata fragments in the aggregate document and host the rest on an external server.
Option 2: Provide all referenced metadata fragments for each MBMS user service in separate, individual documents.
Option 3: Encapsulate all but one of the referenced metadata fragments within the aggregate document, with one fragment linked externally.
Option 4: Contain all the referenced metadata fragments of each MBMS user service description within the same multipart MIME structure.
Explanation: This approach ensures that each aggregate service announcement document is self-contained, making it easier for clients to access all necessary metadata without needing to fetch additional resources from elsewhere. This aligns with efficient resource management and streamlined service initiation in MBMS environments.
