I finally found out what the issue is with this [1] situation. My issue
with it is that IMHO it is not good to see the unclassified road
rendered on top of the primary_link road. I made a test here [2] where
the left primary is a primary_link and the right primary is a primary
proper. Apparently mapnik's renderering rules state that primary_link
roads should be rendered below unclassified roads. I haven't inspected
the rendering rules in detail (I'm also not familiar with them) but I
have seen that tertiary_link roads are also rendered below unclassified
roads. I expect that any *_link road is rendered below any other (or at
least motorway - unclassified) road.
Is this behaviour of mapnik wanted? As I said: IMHO it is not pleasing
to the eye to see the unclassified road rendered on top of the
primary_link road. In order of priority, a *_link road is just below its
* counterpart but above the next lower road (so primary -> primary_link
-> secondary).
