The thing that attracted my attention to this was the direction of the 
way not being used the same way as standard practice .. and as 
documented in the international and national standards.

Within OSM .. I've checked 
http://wiki.openstreetmap.org/wiki/Key:incline - that sets a 'standard' 
for the incline direction.

I'm tempted to simply add the information to the wiki for steps. The 
past discussion on this topic  is from years ago. I'll think about it.

Humm slack. That is a Draft proposal from December 2009 ... I'll contact 
the proposer! Try to advance teh steps bit as I understand that need.
