So, then, the recommendation should be that when extracting data, this
same procedure is followed, and if not, those ways should be marked
incomplete in a way that as much as possible doesn't interfere with
current tools. Making a node-id negative, which in other tools is used
a as a cheap "flag", therefore becomes a non-option. It also runs the
risk of those negative-ids becoming entered into a database, as
So a "key=value" pair like "incomplete=true" or "status=chopped" would
be my favorite.
