[Talk-GB] addr:place cleanup process

[Neil Matthews]

Hi Rob,
I guess the important issue would be if there is both an addr:place and 
an addr:suburb.

This is my local overpass query for place/suburb combinations: 
https://overpass-turbo.eu/s/1f2L

What are you recommending for industrial estate names / retail parks 
within a suburb? They seem to be the most obvious conflicts to me -- 
they have addr:suburb and addr:street -- but they are set back -- 
addr:substreet seems a bit of a stretch, but maybe it fits?

Cheers,
Neil
