The class Entity is not a RTM class, but derived from
RTM_LocatedNetEntity. Therefore, the extension (references to
GmlLocations etc.) is made from a railML class and not from a RTM class.
From content point of view you are right: While RTM does not have
references to specific location extensions like GML or track, railML
model has. However, considering the introduction of length information
in RTM NetElement as described in forum entry [1], a reference to
"trackPosition" and "trackSection" is no longer needed and can be
removed from the model. Further, in forum entry [2] I suggested to
introduce NetworkLocation as new RTM EntityLocation sub-class.
