[Tagging] Aerialway stations

[dktue]

Hi,

I was wondering why there's no way to distinguish valley and upper 
stations of aerialways in OpenStreetMap.

Usually an aerialway consists of

  * one valley station
  * zero or more mid stations
  * one upper station (or "mountain station")

What do you think you tagging this information with

  station=valley_station/mid_station/upper_station

?

Cheers
