[OSM-newbies] Which relation?

[Russ Phillips]

Hi,

I'm trying to map a playground. It has a fence around most of it, but
not all of it. I've added ways, tagged the fence and the gates, but
now I'm not sure how to mark the boundary of the playground. I imagine
I need to put all the ways that make up the border into a relation,
but I'm not sure which one to use?

Boundary [1] sounded ideal, but the wiki page strongly implies that
it's for administrative boundaries.

Any thoughts?

Russ
