[Tagging] highway=residential_link

[Gerd Petermann]

yes, a missing name should be no reason for a highway=residential_link.

During the last days I've reviewed the remaining highway=residential_link
roads, a few of them are quite special, so I fully understand that mappers
have the idea that residential might not be correct, esp. when they
believe that a residential road requires buildings close to it, which in my eyes 
is also not mandantory.

So, I see two possibilities:
1) change the wiki(s) and validators to make absolutely clear that
the _link suffix should not be used with other than the major roads which are now
documented or
2a) change the wiki(s) to tolerate suffix _link for all types of minor ways
(also footway, service etc) with the advice to use them 
for 
- roads that split at junctions
- shortcuts before junctions
(both with pictures)
- maybe more  ?
without forcing this suffix for those roads.
2b) tell data consumers, QA tools etc. to treat the roads
similar to those without the suffix.

pro 1): easy to do
contra 1): many users will not care about what is written in a wiki, so
edit wars are possible

pro 2) : less confusing for those who like the duck test 
(if there is a tertiary_link there should also be a xyz_link)
contra 2): more work for many people, hard to verify 
reg. 2b)

So, my proposal:
Let's do 1) and I'll try to keep an eye on Taginfo to 
warn mappers when they use the _link suffix for 
a minor road as long as we don't implement some kind
of automatism for that.

This is not the only example when a residential road doesn't have a
name. Keep in mind this is specifically why addr:place was invented -
there are villages (in quite a few countries around Europe, for
instance) when streets have no names, yet they are still residential.
The QA software you use makes wrong assumptions.
