Example:
  ?x t:intervalCotemporal ?y    Matches interval  ?x  and interval  ?y  such that  ?x  and  ?y  are equivalent. 
  ?x  and  ?y  can be defined as intervals using either times or points (though they must both be defined using the same mechanism). 
 I.e., Intervals  ?x  and  ?y  both start at the same time  and  end at the same time  or  intervals  ?x  and  ?y  both start at the same point  and  end at the same point.
