+An xApp can use the SDL for two things:
+- persisting state for itself (in case it fails and recovers)
+- making information available for other xApps. The xApp would typically write using SDL directly.
+- The consumer of the data could also use SDL directly or use an access library like in the case of the R-NIB.
