Sorry - I had missed that in all the discussion about unclassified.  In
that case I think unclassified meets what I was talking about for
quarternary ( below tertiary, above residential).

So probably the renderers need a way to show unclassified as less
important than tertiary.

And perhaps 'residential' should be redefined as "only used by people
who are traveling to a location on that road or a less important road
that branches off it", removing the 'residential' notion.
