Introduction

Normally <netElement> which is referred from <operationalPoint>/<spotLocation>/@netElemetRef is modelled as follows:

It’s a non-linear <netElement>. Therefore, it does not have a child <netElement>/<associatedPositioningSystem>/<intrinsicCoordinate>/@instrinsicCoord=”1”
It’s an aggregating (composition (external link)) <netElement> of either Meso or Macro <level> of aggregation. It aggregates everything that is “inside” station.

Some <infrastructure> however can be directly related to the station and be “outside” of it. A descriptive example is a distant <signalIS>. This <infrastructure> element is located on <netElement>s that can be not aggregated into the one referred from <operationalPoint>/<spotLocation>/@netElemetRef.


Overview	Element is inside the `<operationalPoint>`	Element is used by the `<operationalPoint>`

Rules

Use topological aggregation for indicating that an entity (signal 69P2) is inside (within) the station (Cranz)
Use <owns*> (<ownsSignal>) for indicating that an entity (signal 69Va) is “used” by the station (Cranz)
