Sounds good to me.

> 1. Supporting A) Residential gardens are of little interest for the
> general map data consumer's leisure activities. Therefore they should
> not be tagged using the leisure=* namespace for reasons of backwards
> compatibility (see 3 below), consistent rendering (see 3 also), and
> descriptive soundness (see 2 and 4).
> 2. Supporting B) They are however a form of land use, so the landuse=*
> tag seems appropriate. Specifically, they're a kind of residential
> landuse, so it makes sense to refine a use of landuse=residential. So
> the combination in B) seems appropriate.
> 3. Supporting A and B) Use of leisure=garden means that renderers cannot
> distinguish between private residential gardens and public or
> fee-private leisure space gardens without deploying extra rules. It
> would be more sensible and backwards compatible to do something else,
> particularly since trac ticket 3302 doesn't show any signs of being
> closed any time soon. Rendering residential gardens in the same colours
> as surrounding residential landuse that -isn't- gardens both looks
> prettier when the renderer doesn't do anything special to support
> residential gardens, and makes for a more consistent-looking map (since
> many users don't care two hoots about tagging residential gardens, but
> their neighbours do).
> 4. Supporting B) The drill-down pattern used here adds an additional
> layer of meaning to areas of residential landuse. What I've been calling
> "iterative refinement" to date.
> 5. Supporting B, but full disclosure...) There are 756 uses of
> residential=garden in the wiki at present,
> http://taginfo.openstreetmap.de/tags/residential=garden , but I've added
> possibly the majority of those myself by changing a great many local
> objects using the erroneous tagging scheme to the scheme I want. There
> may have been ~100 uses before, which is why I'm listing it near-last.
> 6. Supporting A and partly B) General sanity-check nod on #osm. See the
> Talk:Tag:leisure=garden page in the wiki.
