I can see that this adds value, but unfortunately it is not fault proof either.

See e.g.:

• 5793.pdf (IdentifierColumn is in the description text).
• 7317.pdf (here there are only few entries not recognized)

I still propose that we merge your suggestion, as it seems to make the code more robust overall.

Thanks @redur for these good observations! This seems to be a new layout type from a company "SOLAB F. Perrin S.A.", that is somewhere in between the Deriaz layouts and the "LayerDepthColumn" implementation. I've created a follow-up ticket for this: https://jira.swisstopo.ch/browse/LGVISIUM-40
