I've been trying to find an explanation of what 'extended-address'
actually means, the examples in the vCard spec seem to omit it.

>From its order in the sequence of the fields in ADR, however, I think
it's reasonably clear that it's more specific than the street address,
so would be something like 'Flat 2b'.  This also seems to be the
common usage in hCard.

For those reasons I'm unconvinced about putting all the address data
available into that one field.

It might be useful if someone could experiment with conforming agents
to see if they can take multi-line imput for different ADR fields?

Can you elaborate on what the issue is there?  Most text on web pages
is formatted, and I think in this context it just means 'with
linebreaks' which fairly simple parsing rules would solve.

My main hesitation about using LABEL is that it isn't part of ADR and
so isn't appropriate for the ADR-without-hCard usages.

I agree that i18n issues make this a bit too strict (I have similar
reservations about the implied-n optimisations  but that's

IMO it may be that the best option is to say that ADR can exist
without subproperties for hCard / solo-ADR use for the purposes of
semantically expressing 'hey this is an address' but then to offer no
mapping to vCard unless the sub-properties are present.
