[Tagging] Bad topology way level 2

[Steve Doerr]

There is a philosophy in some parts that the roads of a particular class 
should form a continuous network with other roads of that class or 
higher, with no 'dead ends'. So primary roads should link to other 
primary roads or to trunks or motorways. In UK terms, 
highway=residential is equivalent to highway=unclassified with the 
additional attribute of having housing along it. So in theory, this link 
road could be considered highway=unclassified.


On the other hand the wiki at 
https://wiki.openstreetmap.org/wiki/Key:highway#Link_roads consistently 
associates _link values with the higher of the two classifications 
connected, so primary_link is correct for linking a primary to a 
residential road.


Basically, these two philosophies are incompatible, and you're entitled 
to choose whichever one you prefer. And therefore to ignore any Osmose 
errors that do not apply to your chosen philosophy.
