[Tagging] bridge:name and tunnel:name

I guess that what we have is another case of two (in reality three) tagging
practices for (nearly) the same thing.
name=* for a tunnel's name that is mapped with tunnel=yes seems to be
common practice (at least 760 motorway tunnels in Italy are tagged this
On the other hand we do have many tunnels, where the road in the tunnel
does have a name, and in those cases that the tunnel does have a different
name from the road we need a tagging scheme, which seems to be
tunnel:name=* if we want to use tunnel=yes on the road, or man_made=tunnel
with its own name tag, if the user prefers this tagging scheme.
We cannot mandate to retag existing tunnels and we need to have at least
one tagging scheme in case of two different names. So be it.
What I would not do is to state that tunnel:name is preferred. I would
point out that we have the two solutions sketched above in case of separate
names for road and tunnel.
