[mkgmap-dev] access rules

Hi all, the thread http://gis.19327.n5.nabble.com/make-opposite-cycleways-option-tp5835586.html made me think about the tag bicycle=designated In Germany this means "bicycle and only bicycles are allowed" http://wiki.openstreetmap.org/wiki/File:120px-Zeichen_237.svg.png I think we ignore this in inc/access. On the other hand, I am missing a simple method to say something like : "ignore all access tags but one" I think setaccess no was meant to be used for that, but it changes only the mkgmap:xxx values like mkgmap:car , and we learned that the use outside inc/access causes problems. Any thoughts? Gerd
