The problem I see here is that RoyalMail lumps two very different
concepts into its system of Thoroughfares and Dependent Thoroughfares.
The one kind of cases you have presented are essentially buildings that
get their own numbering. Something like:
'Dependent Thoroughfares' is rather a misnomer for them because
the address part is not a street.
Then there are the other cases, where there is really a side street
that gets the extra house numbers. Example:
Instead of finding a single addressing schema to fit the RM address in,
I would suggest to handle these two cases differently.
Personally, I'd be pragmatic and just use addr:housename + addr:housenumber
for the first case. The other possibility would be to explicitly allow
addr:place and addr:street to go together and define that in that case
the housenumber refers to the given place but the street must show up
in the address.
For the second case, addr:street + addr:parentstreet makes more sense. It
might not have been my choice of words but being used already is an argument.
It might be worth looking around if the concept of two streets in the address
is used anywhere else in the world. I don't remember that it has ever come
up so far.
