Maybe I wasn't clear, I'll try to explain it again: the only true
"entities" in osm are nodes, ways and relations, the rest depends on
the interpretation of tags. Given that many mappers mix what might be
perceived by some as different "features", we can't even know if the
proprietary tag is a feature on its own or a property of one or more
of the other features/entities. It's all about interpretation and you
can't interpret a tag with unknown meaning or referring to a database
you don't know.

Cheers,
Martin
