[Talk-GB] addr:place cleanup process

[Alan Mackie]

I believe substreet is currently being proposed as any level of addressing
below (sub) the street but above the housename/number. So it would fit in
this case?

Although all the retail/industrial estates that come to mind for me seem
like they'd qualify as equivalent to suburbs in their own right.

P.S. sorry for the double email, forgot to reply all rather than reply.
