you're right - i should have said ways can't be transparently modelled
using relations in the 0.5 database structure.
you could use role for ordering, but the ordering would have to be
imposed client-side. the client also has to deal with whatever meaning
is assigned to other relation members of the way or members with
non-numeric roles. its much easier for the client with ways...
relations are an incredibly powerful structure, which can be used to
model just about anything. whether they *should* be used is a
different, mostly non-technical, discussion. for example, it is
possible to build a turing complete computer with a single, incredibly
powerful instruction (subleq / subneg) but that doesn't mean i want to
program it :-)
