Why do you say that no castle_type is documented? castle_type is well
documented including good pictures (see either of the links above) and yes
defensive is the subkey for a "real" castle or fortress if it is a very
large stronghold.

The inital situation was a little different: There was only the key
historic=castle and it was commonly used for anything that looked even
remotely like a castle. In order to better distinguish those objects, the
castle_type subkey was introduced.

Actually it is not that easy to distinguish between "real" castles and
similar buildings in Europe. Many medieval castles were later converted to
more comfortable living places (palaces, stately homes) but retained all or
a part of their defensive buildings or only a few as decorations. In the
19th century, stately homes were built with pseudo defensive installations
because it was fashionable to have a romantic touch.

So if you have a scientifically precise defintion, it is likely that most
mappers will tag it otherwise by their impression anyway. Therefore I think
that a very general tag historic=castle and a subtag for refinement is a
better idea, even if the actual meaning is more like "castle-like building".
