text: Shouldn't this way (highway=footway) be more appropriately tagged?
  
  The way is part of a LCN-bicycle-route, relation 3322620, therefore some tagging allowing cycling seems required.
  
  I stumbled over this, browsing the opencyclemap for edit-hints on relations in general (no survey). 
  
  Incidentally, the route does not appear very "route-like" as the ones I'm familiar with so far. Apparently it merely reflects plain bicycle markings, but maybe it serves a purpose (in GB).
