Dear all,

in consequence of the first post about this topic in the interlocking schema the element <trackIL> was introduced, which
has a 1:1 relation to a <track> in IS. At the same time a <tvdSection> has a 1:n relation to <trackIL>.

The second step to cleanup the references in IL shall be the introduction of <endOfTrack> which defines a limit of the
signalBox either by a physical "obstacle" (bufferstop) or the end of supervision by a final trainDetectionElement. This
<endOfTrack> element would be needed as possible <routeExit> or <routeEntry>.

The proposal is to have a type attribute with enum (physical, endOfSupervision) and a <refersTo>@ref into IS depending
on the named type, i.e. "physical" ref to <bufferStop> and "endOfSupervision" ref to <trainDetectionElement>.

See also attached illustration.
