crossSection: ocp vs. tunnel

• A tunnel has an attribute crossSection that means something like clearance profil.

• An ocp has to be referenced on a track with help of crossSection element as part of trackTopology.

'''These two occurences of the same word have a totally different meaning.

'''Please provide some other term for one of this issues.

My idea: rename crossSection attribute in tunnel element to nominalWidth.

Proposed solution railML 3.1

Neither the tunnel cross section nor the OCP cross section have been modeled in railML 3.1.

Proposed solution railML 3.3

The term "cross section" is well known and established for describing the size of a cutting plane of a tube. Therefore, this term is being used for an attribute in the newly introduced element //overcrossing/tunnelResistance (see #563 (closed)).

Proposed solution railML 3.x

When a use case requires the implementation of an Operational Point cross section, the resulting model has to consider alternative names/terms for the modelled information.
