 +====== Editing Hold Event Duration ======
  
 +The "​event_duration_max"​ attribute of the "<​point>"​ tag defines the maximum allowable time between touch point events. Similarly "​event_duration_min"​ attribute defines the minimum amount of time between touch point events
 +
 +In the example below event_duration_max="​200"​ is used to set a time between touchBegin and touchEnd event in the "​n-tap"​ gesture. This means that ANY touchEnd event that occurs more than 200ms after a touchBegin event will not meet the matching criteria and therefor cannot be part of the TAP gesture.
