The tests I apply in such cases, are:

        What would I type into my computer's address programme (or
        calendar, for hCal, and so on), if entering the details

        If I were to print an address label (to attach to a postal
        packet, say) what would I want my computer to output?

To me, those make it clear that the correct data is, in the example
given, "PO Box 5674"; note that other valid UK postal addresses might

        BFPO 1234

        Freepost ABCD

        Bin 21
        Acme Mail Services

all of which have "post-office-box" data as their first line.
