[Talk-GB] Dual Aperture Postboxes

I noted today a number of post boxes with two apertures, one for stamped
mail, the other for franked mail. Each side of the box has a separate plate
& distinct refs.I would have expected these to have been mapped as
"ref=RF1 1;RF1 2", with some explanatory text to explain that this is one &
the same post-box.

I find that one such has been mapped as two nodes placed directly on top of
each other:

   - https://www.openstreetmap.org/node/1149760519
   - https://www.openstreetmap.org/node/1149765602

This is not wholly unreasonable, there are functionally two different
posting places located in a single post box. It also shows that the OSM tag
name which is perfectly accurate about 99.99% of the time, isn't totally
precise.

(Complete aside: This is the sort of PITA I was always experiencing in
db-design; and equally business folk always will tell you the equivalent of
"all post from one post box is treated the same". In the extreme form you
get US software firms writing banking systems which don't acknowledge that
more than one currency exists).

Anyway I look to Robert to cut this Gordian Knot one way or the other.
