Secondly, some addresses contain two street names, a main

anomalies, a single postcode should only cover one main street, but
can include more than one dependent street.
These are actually quite common, and having had a look at the error list
for my local area nearly all of them are due to this - the address is on
secondary street accessed from the main street with which it shares a
postcode. Here's one, for example:
https://www.openstreetmap.org/way/304095650
(The tool will not see the
dependent streets as different if both streets are tagged, either as
addr:substreet and addr:street or as addr:street and
addr:parentstreet.)
Which is the more correct usage here? Do we
a) tag the dependent street as the addr:street, and the main street as
addr:parentstreet, or should we
b) (following Royal Mail practice as found in the PAF), tag the
dependent street as a addr:substreet and the main street as addr:street?
My personal preference would be the latter, it's not only consistent
with official addressing practice but it's also how most people perceive
these kind of addresses as well. But, on the other hand, most map
editors are likely to use addr:street for the dependent street, simply
because the editor UI doesn't make it obvious that addr:substreet is a
possibility. So it might be simpler to fix these by adding
addr:parentstreet as necessary rather than trying to get everything
pedantically correct.
I've the same problem on a number of cases and certainly
addr:parentstreet is just wrong ... the sub street is actually part of
the house detail rather than the street, so similar to 'Flat 1 Block of
Flats' ' Street' but this still leaves the 'addr:street' or
'postal_code' question for the tag on the primary street. Having SOME of
these tagged 'addr:parentstreet' is simply wrong ...
