[Tagging] large roof garden

[Blake Girardot]

Hi Volker,

I generally tag them with:

roof:material=grass

or

roof:material=plants

http://wiki.openstreetmap.org/wiki/Key:roof:material

But in this case and maybe in other smaller cases it looks like we 
almost need a:

roof:use=*

Where the roof is used for something besides just covering.

Either way, I don't think the roof:material=* tags would be incorrect.

By the way it looks like the roof or the tunnel that goes under it could 
use some layer=* tags as well.

It might even be more accurately tagged tunnel=building_passage

Cheers,
Blake
