Change log


added Semantic definitions at the entity

An abstract entity defining common information about horizontal, vertical and cant alignment segments.

NOTEĀ  The start and end tag are defined as annotations, not as referents along the alignment. Only absolute distance expressions are in scope, not distances ahead or behind a referent, such as a station. However such information can be exchanged as tags. Attributes
