All of those examples appear to allow regular pedestrians (foot=yes), 
which is common. I am asking if there are any places where walking is 
allowed *only* if you are pushing a bicycle, i.e. "no bicycle, no 
access". IOW, where your joke about dogs isn't a joke.

(OT: Airline transponders may be IFF — note the capitalization — 
although I wonder about that because I always think of IFF as more a 
military thing. I'm not sure if civilian transponders are really meant 
to *identify friend or foe*, or if they're more just "transponders".)

Right, that's what I was suggesting, because the only plausible 
interpretation I can come up with for foot=no + bicycle=dismount is that 
you may traverse the way [on foot] iff you are pushing a bicycle. The 
question was, does that ever actually happen? I'm not *quite* willing to 
rule it out...
