[Tagging] RFC - obligatory usage - bicycle=obligatory

[Volker Schmidt]

1) Please no new tag that breaks existing tagging.

2) Please can you give me the missing link in your proposal ("But it
remains disputed (*Insert Link*) whether that obligatory cycleway has to be
mapped as a separate way ...). I am interested in that for a different
purpose which regards the mandatory-ness of the bicycle lanes in Italy
(they are legally cycle-paths with mandatory use).

3) For me it seems that the bicycle
<https://wiki.openstreetmap.org/wiki/Key:bicycle>=use_sidepath
<https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Duse_sidepath> is the
correct approach, exactly because it is impossible to decide whether a
cycleway is mandatory or not without saying with respect to what road the
requirement is correct.
Let's construct a case: you have two parallel roads. In the middle between
the two there is a cycleway that is labelled with "mandatory". How do you
determine the weighing of the roads for your bicycle routing. Either on the
cycleway the "mandatory" tag has a value that defines which of the roads
are affected, or the roads themselves are labelled with
"bicycle:use_sidepath=yes/no" (note that this is slightly different from
bicycle=use_sidepath, but this is less important)
