Hi, 1. I'll add "readonly atttribute version drmsVersion" to the MonitoringSession if nobody disagrees. The DRMS (drmsInfo) itself can be retrieved from SessionManager. The DRMS (drmsInfo) depends on the library, the version depends on the session at the moment. We have a pointer to it already in the MonitoringSession description header. 2. We could also put "readonly attribute string drmsInfo" to MonitoringSession which would allow one to write an implementation which could handle two or more different DRMS. If not IMHO this would not be possible (at least we would just have one "drmsInfo" which is correct in just one case).
