Okay. In this case I can rename to proposal page to "addr:range".

This new tag:

- applies to nodes and closed ways that have addr:housenumber
- "addr:range=n" means every nth house is counted in a range
- "addr:range=even/odd" means every even/odd house is counted
- "addr:range=all" means every house is counted (default value for a 
housenumber tag with a hyphen in it if no range is given).
- "addr:range=no" means that the housenumber tag is NOT a range of values but 
rather a single housenumber.

"addr:range=all" is the default  because that is what the wiki says and what 
software like streetcomplete suggests. Many buildings with multiple 
housenumbers are tagged like this.

However, software can create different defaults for different countries. For 
example, in the UK a hypenated address most probably means a range of even/odd 
addresses (so "addr:range=2")

What are your thoughts on this?
Also, I had linked the talk-gb thread, which discusses how addr:interpolation 
on closed ways and nodes is already standard. That is the problem with 
suggesting a new tag. This proposal would now require informing multiple 
mappers to switch up the taggong scheme.

Thanks,
IpswichMapper
