[Tagging] defining service on railway=tram

[Jarek Piórkowski]

Hi all,

Last month I wrote about defining service=* tag values for
railway=tram ways, which were previously not defined and used somewhat
varyingly in the wild. Thanks Mateusz for your help refining the
definitions!

I have now written
https://wiki.openstreetmap.org/wiki/User:Jarek_Pi%C3%B3rkowski/Key:service
with a draft of new section I am suggesting to add to Key:service.
Please feel free to edit that wiki page, or comment here on mailing
list.

Should this go through proposal process? It's not defining a new tag,
but it is suggesting newly defined meanings that in some cases differ
slightly from current use (in particular not using service=spur).

Thanks,
--Jarek
