Sorry I had to focus on other things for the last few days, thank you all
for your input.

Agreed, I'd have to find that out from UTA before applying that information
to any mapping onto OSM.

the public server does not have as many attributes filled as the file they
provided me with (and which I since uploaded to
http://lima.schaaltreinen.nl/tmp/ - pick either the zip file or the four
shapefile parts)

Yes, it is.

Yes, it's used in their real time vehicle location API and they also have
an automated voice system that you can key the number into to get schedules
for the stop.

That was my thought too. There have been a few overwrought tagging
proposals lately, the public_transport one and the lanes one come to mind.
As long as they are backwards compatible with what normal mappers use I'm
fine with it though. I'm just going to go ahead and use highway=bus_stop.
