GSD : Generalised Symmetric Difference

RANGE: (NUMBER|VECTOR)[,RANGE]
VECTOR: <NUMBER, NUMBER>
NUMBER: number of intersection, negative number are added to total number of object+1

The minimal number of objects is three.

Interunion

syntax is

interunion { 
  OBJECTS...
  [range{ RANGE } ]*
  [OBJECT_MODIFIERS...] 
 }
