Add data types for platforms and ramps

will be extended with an element for modelling platforms, ramps and related facilities.

The new element describes the part ("section") of a track which can be used for the exchange of passengers, goods or similar.

Attributes for this new element include:

• position information: defines the starting position and direction of the serviceSection

• length: the section length which is defined as the actually usable length (NOT the physically existing platform/ramp which can be longer)

• height: the objects's height in mm above rails (for feasible types only)

• type: enumeration of

• "platform" (passanger platform)

• "ramp" (ramp for loading / unloading goods)

• "maintenance" (maintenance facilities e. g. in a depot)

• "loadingFacility" (Goods can be (un-)loaded from the wagon's top / underfloor)

• "cleaning" (washing facility for cars and engines)

• "fueling" (facility for re-fuelling of engines)

• "parking" (section for parking of rolling stock)

• "preheating" (electricity or steam for pre-heating purposes)

• "other"

• side: right, left (seen in positive mileage direction)

Each "serviceSection" can have multiple types. Tracks with platforms on both sides need two elements to force the definition of different platform names.

Additional semantics:

• name: the name contains the platform number (e. g. "3")

• The associated OCP can be de-referenced from the OCP's trackGroup

NOTE: Depending on feedback on short notice from possible users of this enhancement, this element may be already introduced in version 2.1.
