   optional_unique_properties
       According to the iCalendar standard, the "duration" and "retreat" properties may be specified at most one
       time  all  types  of alarms; if one is specified, the other one must be also, though this module does not
       enforce that restriction.

   mandatory_unique_properties
       According to the iCalendar standard, the "trigger" property must be specified exactly  once  for  an  all
       types of alarms; subclasses may have additional required properties.

       In  addition,  the "action" property must be specified exactly once, but all subclasses automatically set
       said property appropriately.
