[Tagging] Extremely long names for highways

[Peter]

Hi all,

we've detecting more and more long names for highways, like I once
reported here: http://www.openstreetmap.org/user/karussell/diary/26055

One example:
https://www.openstreetmap.org/way/51109811

As discussed there the names are from official source, but should we
really include this in the name tag?

I've posted this to the OSM forum already and there seem to be a bit
controversial answers :)

But I agree with 'SomeoneElse' that description should not go into the name.
What is common sense here?
If that is correct, how to proceed - adding OSM notes to these ways to
let the author correct these?

Kind Regards,
Peter
