+/** Constructor.
+This Active Object has a priority of EPriorityHigh + 1. This is to ensure 
+that, when a final packet is sent, the RunLs are executed in the following order:
+1/ signaller (EObexFinalPacketStarted)
+2/ activeRW (the final packet actually being sent)
+3/ signaller (EObexFinalPacketFinished)
+The priority chosen is EPriorityHigh + 1 because the priorities of the 
+transport controllers' writer (CActiveRW) AOs tends to be EPriorityHigh. 
+As long as this is the case, our guarantee holds. Our documentation says that 
+new licensee transport controllers must have writers with priorities that 
+continue to support this guarantee.
