Stop sell, closed to arrival and closed to departure updates will be sent through using the RestrictionStatus node. Below is a set of scenarios where SiteConnect will send an update through.
Note that stop sells, closed to arrival and closed to departure can be sent separately by SiteConnect so their status should be assumed as separate. For example a message which has a 'Open' status without a 'Restriction="Arrival"' should not change the state of the closed to arrival.
