-  # problem with RelationMember is that it may link to any one 
-  # object (a node, a way, another relation), and belongs_to is
-  # not flexible enough for that. So we do this, which is ugly,
-  # but fortunately rails won't actually run the SQL behind that
-  # unless someone really accesses .node, .way, or
-  # .relation - which is what we do below based on member_type.
-  # (and no: the :condition on belongs_to doesn't work here as
-  # it is a condition on the *referenced* object not the 
-  # *referencing* object!)

-  belongs_to :node, :foreign_key => "member_id"
-  belongs_to :way, :foreign_key => "member_id"

-  # NOTE - relations are SUBJECTS of memberships. The fact that nodes, 
-  # ways, and relations can be the OBJECT of a membership,
-  # i.e. a node/way/relation can be referenced throgh a
-  # RelationMember object, is NOT modelled in rails, i.e. these links
-  # have to be resolved manually, on demand.
