TrainProtectionElement vs ETCS

Description

It must be clarified how ETCS based systems shall be modelled. In particular, the usage of <trainProtectionElement> for ETCS based systems should be questioned.

Background

The discussion was initiated at the railML ETCS use case working group meeting on February 26, 2021.

Proposed solution railML 3.2

<trainProtectionElement> shall only be used for national and/or legacy train protection systems. ETCS based systems must not be modelled using <trainProtectionElement>.

This has to be clearly documented in the element annotations.
