OK, at least that is clearer than the working pages of the wiki.  But I'm
still having difficulty comprehending one thing.
I have an actual route, and I'll designate segments of ways with letters
(and simplify it a lot).  Platforms are mapped
but stop positions aren't (somebody who thinks they shouldn't be there
cleaned up after me).

    A  B  C  D  E  F........ M  N  B  C  D  E  F

Starts at A, terminates at F.  It repeats B C D E F at the end of the
route, but doesn't pass A.  There's a stop at A (start
of the route). There's a stop at C which is ignored the first time the bus
passes it but is stopped at (on request) the
second time (and appears in the timetable). It stops at F both times.

So the stops are going to be the ones at  A C F ... C F, in that order, in
the relation.

It's kinda hard for me to figure out what's going on from the relation, and
I know the route.  Without stop positions
it seems to me to be a lot of work for a router to figure out as well.  I
think a typical consumer using the query tool
would be completely baffled by the relation info returned.  But you're
telling me this is correct?  If so, that's what
I'll do.
