Yep. We have the perennial problem with OSM that some aspects of
geometry are expressed in metadata (i.e. tags/relation structures)
rather than in attributes (as lat/lon) - in particular, layers and
MapCSS has traditionally taken the attitude that stylesheet authors
shouldn't have to worry about this and has therefore automagically
abstracted them away.
