<div>Logically, you need to know the lower of the two classifications being linked, and it may also be useful to know the higher of the two being linked. So I record that information in links_lower and links_higher tags. Then it can be rendered very neatly.</div>

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.<br>
<br>
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).<br>
