I'm not convinced. A value of yes as a stand-alone item is meaningless but a value of hedge is sufficient to indicate we're talking about a barrier.

However, you suggest building=residential as possibly being redundant. In fact, I'd turn this on its head and make landuse=residential (with the exception of moles) redundant. The only residential landuse is directly under a building but by using landuse=residential, such areas cover gardens and highways - which are clearly not residences. > > The discussion recently on how a 'university' should be tagged probably > encompasses all of the circularity with the current tagging practice, > and where the hierarchy of tagging could best be agreed. > > Campus area === landuse=university > Some universities are on several campuses, but there there are other > landuse areas between, AND there should be no other landuse areas > contained within the campus area, other tagging should identify water, > woodland, grass, building, and the like WITHIN the area.
