Hello, It seems this issue is about ready for closing, again after insightful discussion. I have suggested a rephrasing in the notes of the requirement in the issue tracker <https://www.w3.org/2015/spatial/track/issues/11> and I have changed the status of this issue to 'pending review'. If anyone thinks the proposed solution could be improved, please make it known.
