# node, ways and relations. This code is here to avoid duplication,
# and allow the extention of the checks without having to modify the
# code in 6 places for all the updates and deletes. Some of these tests are
# needed for creates, but are currently not run :-(
# This will throw an exception if there is an inconsistency
