[ML3] My interpretation of that section is that it warns clients that a postal 
address could appear in either format in an RDAP response and, therefore, they 
should be prepared to handle both of them.

But I'm pretty sure that clients typically consider the unstructured version 
only when the structured one isn't available. For an implementer, it's much 
easier to start with structured data and aggregate/manage it as desired rather 
than the other way around.

I don't know what "typical" is, but my client will display both if both are 
given... but I have never seen any registry do that.

While I think supporting unstructured addresses is an absolute requirement, it 
does occur to me that even registries that cannot fully support structured 
addresses do have the country and sometime region in a semi-structured form. 
Therefore I don't think it is unreasonable to allow unstructured addresses and 
at least these two fields in a structured form... it isn't great, but it is 
better than nothing.

It is also my understanding that one of the reasons unstructured addresses area 
allowed in vCard is that they represent what can be written out on a postal 
envelope for an economy. (I don't know what JSContact does here). It is one 
thing to have a postal address in structured form, but if you cannot use it on 
a postal envelopes that seems to be a bit odd. I think we westerners tend to 
think that structured addresses are obvious in postal envelope form, but that 
is not true for many places in Asia where writing direction on both axes is not 
the same (as ours).
