The arguments for how to tag a footway and a cycleway contain a number of 
boolean examples.
Either you are permitted to drive a car down the footway, or you are not.
You are permitted to cycle on the footway, or you are not.

The trinary response from my culture would be "it's only a problem if you are 

no_exit is boolean until we consider flying as a possibility

and the tags needed for certain Australian road conditions 
dry_weather_only and 4wd_only are certainly boolean.

so having dealt with boolean, and discussed enumeration (house numbers)
do you have any further suggestions after numeric, string and free text?
