OK: going back to basics here, as I may have jumped to some conclusions
and/or missed some details:

In the latter case, you may have Property Pages for street name, postcode,
city, and country, and these Property Pages potentially have [[has type]]
properties of their own, letting you (for example) specify that "city" is a
page reference whereas "street name" is text. I'm assuming that the same
holds true for the subobject? That is, for each label=value pair in the
subobject, the label is the name of a property page that provides
information about how to interpret the value.
As well, there's potentially a property page for "street address". In the
latter case, it [[has type::Page]]; what does it have in the former case?
I'm guessing something like [[has type::subobject]].
Question: can you define a "property subobject" instead of a property page
for a subobject's property/value pairs? That is, on Property:street
address, can you say something like:
[[has value::subobject]]
{{#subobject: street name | has type=Text}}
{{#subobject: postcode | has type=Text}}
{{#subobject: city | has type=Page}}
{{#subobject: country | has type=Page}}
...and thus define the types of the property values that appear in a
"street address" subobject all in one place?
