SIRI feed contains empty stop point refs

[leonardehrenfried]

The SIRI feed available from https://efa.sta.bz.it/siri-lite/estimated-timetable/xml contains <StopPointRef> elements without any content.

This will make them impossible to apply as we definitely need the stop ids.

A correct element looks like this:

cc @rcavaliere Can you add the appropriate labels?

@leonardehrenfried how often does it happen? I would match only the journeys for which this is possible, and skip the others. So we can see for which journeys we have mapping issues.

[leonardehrenfried]

So out of the 32614 calls in the file 274 don't have a reference to a stop point.

I will be working on journey-based statistics.

[rcavaliere]

OK, these might be edge cases. Let's try to match what we can, if then see the data and journeys, we can then better understand the problems

[leonardehrenfried]

There are 121 journeys where this happens. Out of 800 that's quite a few.
