David, thanks for offering some updates.
By the way, I am not asking questions because I personally want the
answers - I am fully aware of how these things work. And because of
that, and because OSM tries to model reality, I believe we need some
kind of anchor-point for our thinking in order to converge on a proper
solution. In many countries postcodes/zip codes are associated with
geographic areas; the UK, as frequently happens, uses a different
paradigm. We need a clear statement of the intention for the addresses
in OSM, and my belief is that they represent postal addresses as per the
PAF. PO Box numbers are not applicable to OSM, as they cannot be related
to a location useful in OSM. The discussion is just about Dependent
Locaiity, Double Dependent Locality, and Dependent Thoroughfare. If we
can define what OSM tag should be used for these three fields, we have a
model which is sufficient for all UK addresses.
Of course, it is an option to decide to NOT represent this level of
detail in OSM. In that case, expect mappers to make up their own
solutions, and this discussion to resurface every few months.
Sub Building Name
Dependent Thoroughfare Name
Dependent Thoroughfare Descriptor
Double Dependent Locality

Everyone who has received utility bills will have their own code, but they are only available to paying customers, as far as the sender is concerned.)
