I would disagree with Christoph's assumption that addresses must be unique.
The purpose of an address is to help someone locate something. It gets
"close enough", with the definition of that phrase varying by
locality/society/observer. ALL addresses, in that sense, are "partial", to
use Christoph's term.
Multiple objects may share an address. In fact, this has just been raised
in the context of cycleways (should they share the name of the street they
parallel?). Other examples have already been given in this thread (the red
shed). And the converse is also true: single objects may have multiple
addresses. Addresses can be many-to-one or one-to-many; a one-to-one
relationship is not required.
Back to the OP, I think the "no" prefix tags are problematic in general
(noaddress, noname). I personally like Martin's proposal of a "no_" prefix.
At least that's easier for data consumers to suss out. So I'd vote for
no_addr:housenumber=yes.
There is, in fact, an address in these cases, so "noaddress=yes" is wrong.
