<div>Well first, tunnel=yes is obviously wrong. We

Obviously? Regarding paths and waterways, especially

"tunnel" is an attribute of an object called "highway", including
the paths in question.<br>
"cave:NNN=*" are attributes of objects "<tt
style="background-color:#dde; white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:natural"
title="Key:natural">natural</a>=<a
href="http://wiki.openstreetmap.org/wiki/Tag:natural%3Dcave_entrance"
title="Tag:natural=cave entrance">cave_entrance"</a></tt>,
obviously speleology and not path oriented.<br>
"cave=*" is not defined.<br>
I know I still have to learn that OSM is fuzzy, but using "cave=yes"
for paths would first need a definition of it in the "highway=*"
page.<br>
<br>
This said, we could wait for years for a rendering of cave=yes, let
alone routing support.<br>
Rendering and routing don't care if it's man-made or not. They just
work or don't.<br>
Why not use the well established tunnel=yes and layer=-n? And cope
with the subjective, cultural, etc. strangeness with an adorning
cave or whatever made up tag?<br>
