[OHM] Route tagging scheme

[Tim Waters]

it's nice to see relations being mapped in such a way within OHM. I also
prefer the first example of showing different routes. One can imagine a
historical router software preferring that too.

I agree that tag changes where the geometry doesn't change does seem easier
initially to put on one object, however I suspect that given some
additional detail, that the road geometry might well change from 1901 to
1961 and so one would have to separate out the ways, and copy and change
the tags (overlapping ways shouldn't matter in that case).  I guess that
buildings could fit the single way model better.

Regards,

Tim
