I agree with Andy here: no tags = no information. Which default is
then implemented in a routing application depends on this application.
To your question about a special tool: how would you know
automatically which access restrictions apply?
The example you pasted seems like bad mapping to me: a gate can't
actually be directly on a bifurcation node. I would strongly recommend
to tag it at it's real position, and if it's two gates (what would be
a possible interpretation of your quoted example) then tag 2 separate
gates.
cheers,
Martin
