Sorry, maybe this is a language issue. In my mind, "height limit" of a
way refers to maximum height *above* the way, whereas "clearance" of a
way infers maximum height *under* the way. Maybe "clearance" isn't the
best word for this - please suggest others.

My main point is that when there is a "maximum height under a way",
this should be tagged as an attribute of that way, not of the ways
that pass under it.
