+// class G4VNestedParameterisation
+//
+// Class description:
+//
+// Base class for parameterisations that use information from the parent
+// volume to compute the material of a copy/instance of this volume. 
+// This is in addition to using the current replication number.
+// 
+// Notes:
+//  - Such a volume can be nested inside a placement volume or a parameterised  
+//    volume.
+//  - The user can modify the solid type, size or transformation using only
+//    the replication number of this parameterised volume.
+//    He/she is NOT allowed to change these attributes using information of
+//    parent volumes - otherwise incorrect results will occur.
+//  Also note that the usual restrictions apply: 
+//   - the mother volume, in which these copies are placed, must always be
+//     of the same dimensions
+
+// History:
+// 24.02.05 - J.Apostolakis - First created version.
