[Talk-GB] Should a place be tagged with a node or area?

I'm really not sure that we should be trying to map these at all. If we do
I think Colin's approach is best: a super-relation of other admin entities.
Not easy to create in the online editors but easy enough in JOSM.

There is very little on the ground to allow verification, and I suspect
many will be rather ephemeral entities.

There are numerous other boundaries which might be of more interest, but
still perhaps not suitable for OSM : school and GP catchment areas; police
authority areas and community policing areas; NHS commissioning areas; etc,
etc.

As ever the question is where do we stop. I think a useful questions to ask
are: "Are these boundaries principally used internally to an organisation
with little or no use outside it?"; "Do the boundaries impinge on people
external to the originating organisation such that reference to these
boundaries is likely to be made regularly?"; "Can people tell you where
roughly where these boundaries lie?.

I can at a pinch tell you the catchment area of my GP surgery because they
have a big map on the surgery wall, and once upon a time knowledge of NHS
DHA boundaries was something I need to know professionally, but for the
most part I dont know anything about the others.
