Similar to the application of the designator in "functionalInfrastructure" or "assetsForInterlocking", we would like to introduce the <designator> also for the RTM <netElement>.
a) If a railML-file is available as input to a tool chain of independent systems, this could provide a common reference for the tools.
Example:
<netElement id="ne_206" length="7889">
<designator register="_tool_01" entry="STC-T101_T201_T301" description="common edge name in all tools"/>
...
</netElement>
b) On the other hand, if railML files from different tools needs to be combined and no input-reference is available, then it is helpful to have an information of the element's name in each tool.
Example:
<netElement id="ne_206" length="7889">
<designator register="_tool_01" entry="STC-T101_T201_T301" description="edge name in tool_01"/>
<designator register="_tool_02" entry="STC-P01_Track1_P03" description="edge name in tool_02"/>
...
</netElement>
