Anything goes for keys and values so those with a navigational interest are
welcome and encouraged to invent new keys and values that do the job
specifically for that usage. Just as piste maps for skiing will require
special tagging for appropriate rendering and use.
The Map Features page on the wiki was an attempt to set some base ideas for
a set of controls related to streets, but they are only a suggestion and as
far as I am aware currently only being used to benefit a few of us who are
playing with rendering using SVG.
If mathematical navigation is your buzz, then why not have a crack at
starting a wiki page specifically covering that aspect.
