+Description:
+		This attribute is used to unregister and delete a previously
+		created trigger from the list of available triggers. In order to
+		achieve this, one should write a positive integer into the
+		associated file, representing the id of the trigger that needs
+		to be removed. If the trigger can't be found, an invalid
+		argument message will be returned to the user.
