Hi Milo and Sérgio,

thank you both very much for your feedback. I think you gave perfect 
examples of the two different approaches that I
came across:

So one approach is to have "leisure=common" areas adjusted to the local 
situation. The other approach is to have circles tagged with 

Since the two approaches are pretty different I really would like to 
know which one is the preferred one. Once this is sorted out we probably 
shoud align the mapping & tagging for easier extraction and processing.
