So far I've thought of highway=footway as a "path" (not in the OSM sense)
that is dedicated to pedestrians, but it's not a road closed to motorized
traffic. For example, a pedestrian passageway through a park, or a
pedestrian bridge over a railway. But if it's like you said, then I guess
that a crossing might fall under that name.

This is nice too. I have no particular preference for any of these methods,
and I wait to see what other people think.
