The comparision doesn't apply well. "no" is a valid value for the "oneway" key. "noname" uses a different key than the one it relates to (instead of using "name=none" or "name=unsigned"). And both tags are definitive, whereas "maxheight:signed=no" (or whatever) is just waiting for a better tooled or experienced mapper to do the survey. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
