[Tagging] Micromapping

[antony.king]

While preparing the proposed playground equipment tagging schema, it
occurred to me that there are lots of instances of 'micro mapping'
where detail is being added to cover stuff like litter bins, gates,
playground equipment, grass verges etc, rather than 'big' stuff like
roads, parks and so on. I don't recall seeing a category for such
things on the wiki - any thoughts anyone?
