[Tagging] aerialway=mixed_lift

[Holger Jeromin]

Hello,

I found the rare but (in winter sport areas) important mixed_lifts with
chairs and gondolas are not rendered on the osm mainpage.

An issue for the rendering style
https://github.com/gravitystorm/openstreetmap-carto/issues/347
suggested a discussion about this tag here on the tagging list.

I see no alternative to add this additional value in aerialway due to
its difference to a chair_lift or a gondola. But a relation would add
unneeded complexity to the feature.

Additional tagging to further define the lift future proof could be
aerialway=mixed_lift
mixed_lift:chair=yes
mixed_lift:gondola=yes

I found a small note about this tag at:
http://article.gmane.org/gmane.comp.gis.openstreetmap.tagging/16695/

> What if there is a mixed lift with chairs that have 4 seats and chairs that have 2 seats?

This could be solved by a prefix
mixed_lift:chair:occupancy=2
mixed_lift:gondola:occupancy=4
mixed_lift:occupancy=3 //for backward compatibility if wanted

What do you think?
