Point (Abstract)
A 0-dimensional node of the network used for the spatial description of the network. POINTs may be located by a LOCATION in a given LOCATING SYSTEM.

LinkSequence (Abstract)
A LINK SEQUENCE describes a path through a network, such as a bus route. It can consist of an ordered set of POINTs IN SEQUENCE (referencing POINTs of a particular type) or LINKs in SEQUENCE (referencing LINKs of a particular type).
LinkSequence is abstract: it is specialised to create specific types of path such as Route, JourneyPattern, ServicePattern, etc.

«cntd» | (pointsInSequence) | (XxxxPointInSequence)+ | 1:* | An ordered sequence of POINT IN SEQUENCE elements that each reference a POINT of the specific type for the LINK SEQUENCE. For example, a ServicePattern holds a sequence of StopPointInJourneyPattern instances that each reference a ScheduledStopPoint, |
