Hi.
I think, the last argument Martin has in his reply is the most important
one:
Tagging the width of steps is simple - and useful independant of other
proposals for mapping steps, if it's equal in general from top to bottom.
But one usual case is, that steps are around a building etc., so they
get smaller upwards (or wider in other cases).
It is not possible to map that simply as attributes, as long as you
don't want to have step-width tagged on nodes (something that is error
prone because of the missing connection from node to one particular
steps-way).
regards
Peter

Any suggestions as to how to represent some steps...
These steps aren't that unusual I guess, but they aren't a staircase. They
form the edges of a piazza-like platform, running most of the way around it.
There are only 4 steps, but they are several of them, up to about 40m wide:
How about using a way for them (between top and bottom) and setting
width=40m
on it?
This wouldn't give the direction of rise; perhaps any solution to that
could also be applied to the "incline" tag.
Or perhaps (if we do use a way for the steps) we could use the incline
tag on the way, and define "incline" on a node to take the values
"top" or "bottom", and use that for the top and bottom of the flight
of steps.
This probably needs the least change to routing software, too.
It wouldn't give an accurate description of tapering flights of steps,
but that could be done with several highway=steps with different
widths.
