Well spotted.

If using methods 2 or 3 from Franc's original email, presumably we'd
also need to add a sequence number (actually two since, as you point
out, each way would refer to segments of two boundaries) for each way,
since a unique boundary ID is no longer unique to the way, once you've
split it up into two or more segments.
