+    \brief  The GateEmptySD is a sensitive detector , derived from G4VSensitiveDetector,
+    \brief  to be used for removing existing SD from G4SDManager 
+
+    - This SD is not exposed to the user. It's sole purpose of existing is to fix issue with 
+      GateMultiSensitiveDetector, for a volume with both SD and actor attached to it.
+
+    - It will not ask for any dynamic memory allocation.
+
+    - It will not be registered in the GateDigitizerMgr.
