Different station tracks in one <ocpTT> for different <operatingPeriod>s (de: Saisonierte Gleisbenutzung)

Description

Discussion during the last TT development meeting: It shall be possible to specify different station tracks for one ocpTT.

Background

The topology reference is similar to the designator register for an ocp which allows the receiving system to retrieve additional information from an external register.

Please note, that the actual topology is not part of the railML file and must exist in or be accessible to the receiving system.

Changes in railML 2.4

A cancelled train or trainPart is written to the railML file including all regular attributes and elements. The `@NEWATTRIBTE` attribute with a value of 'true' allows the importing system to process this information accordingly - e.g. to inform passengers of a cancellation.

railML elements

The following new attributes are available:
 1. ` railml/timetable/trains/train/trainPartSequence/topologyReference `
 1. ` railml/timetable/trains/train/trainPartSequence/topologyReference/@register `
