In respect to possible future use of the timetable-schema as an interface
for programs that treat with actual trains and not only with longtime
planning it should support the possibility to give delta-informations for
existing timetable data. So it would be useful to add the proposed
attribute <status>.
The <date> of the last change would be used in this respect to decide for
multiple changes which one is the last, that is to say which one is valid.
