Hi John,
Maybe I'm a little confused, but given this discussion & looking at a recent
change to the Australian Tagging Guidelines on the wiki, has the network/ref
tagging changed from your original proposal? I thought the network tag was for
removing the letter prefix from the number, but are we now doing network=A,
ref=A1? Isn't this just the same as before but with an extra tag?

I think this is why I am concerned about adding the addr: tags to the ref
relations, is it not redundant data given that we have suburb boundaries, we
know with reasonable certainty that a node is in what suburb/state/country? I
see changes to the cycle route tagging guide says to potentially add all
suburb/state/country tags. It's like adding is_in tags to all nodes/ways even
though we have suburb boundaries (thanks again Franc!!).
Is it some limitation of the mapnik styles that caused the US guys to create the
similar tagging scheme? Ideally it could be solved with code instead of adding
to the burden of tagging.

Also looking at the the text for the Route section of the Au tag guide page, I
think it is too verbose & mixes guidelines with reasoning & thoughts. Given it's
a wiki, I might work on wording and make some changes (kind of similar to the
OpenSource mantra of stop whinging, show me some code). The gist of it is leave:
* mention old & new shield system
* tagging example
* Highway Refs (but name it something like "Network Refs" or "Sign Shield Refs")

Move "Minor Roads" sentence to the Naming Streets sections (since that is what
it is).
Remove the distinction between Major & Minor Highways tagging, to something
simple like: If a named route & a numbered route follow the same ways, combine
into a single relation. If they finish at different spots or take different
paths, create a separate relation for the named & numbered route.
Example of a combined:
 name= Thingamajig Highway
 network=C
 ref=123
 route=road
 type=route

Thoughts / better ideas?  BlueMM
