I was thinking you were asking about another new placeholder
(namely receiver_*) of which conception I was foolishly fond
or shall I say proud.

That's right. They needn't even be adjacent. And they can
occur multiple times in order to refer to parts of the same
address multiple times.

Not at the moment. That's currently a limitation which I will
get rid of. The definition is now:

        u"""part of a generic address, cached, selected from database:
                args: optional template//optional selection message//optional 
cache ID
                template: %s-style formatting template
                message: text message shown in address selection list
                cache ID: used to differentiate separate cached invocations of 
this placeholder

IOW, if you want to "start" a new "instance" of the
placeholder just use a new cache ID. Note, however, that once
you start using any cache ID you'll have to use that ID for
_all_ parts of the same instance:

instance 1, first occurrence, this will show selection and cache:

        <$gen_adr_street::the street=%s//Please select an address !//inst1$>

instance 1, 2nd occurrence, will just use the cached part:


(note that you don't have to - but can - repeat the message)

instance 2, cached seperately, again selected from list:

        <$gen_adr_country::country=%s//Please select an address !//inst2$>
