Actually, we will have more selectionSequenceId than selectorId because 
each different observation point will require a different 
selectionSequenceId, even if the sequence of selectorId is the same. 
Now, on the top that, we require some more selectionSequenceId if the 
order of the selectorIds is changed.

selectionSequenceId

   Description:

      From all the packets observed at an Observation Point, a subset of
      the packets is selected by a sequence of one or more Selectors.
      The selectionSequenceId is a unique value _per Observation Domain,
      specifying the Observation Point and the sequence of Selectors
      through which the packets are selected_.
