I've assumed that ramp should be used only with some steps, but actually 
the definition in the wiki 
(https://wiki.openstreetmap.org/wiki/Key:ramp) it's wider: " It's 
*usually* used on staircases".

To me it seems quite a useful option.

But would it be ok to use it on a node instead of a way segment?

Thanks,

Ale
