And then fully document the castle_type used. As no other castle_type is
documented, it would be a first.
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.
There is no separate individual wiki page for the value of each castle_type,
so 'not fully documented'.
And it is 'poor'. As an example ..the difference between castle_type=fortified
and castle_type=defensive? None?
Wikipedia has a fair amount on castle - https://en.wikipedia.org/wiki/Castle
Things on the castle_type OSMwiki that should not be there (my thoughts) are
Palace -
Buckingham Palace, London, UK is tagged as a building
http://www.openstreetmap.org/relation/5208404
In the original building proposal palace was mentioned as a type of building.
https://wiki.openstreetmap.org/wiki/Proposed_features/building#Original_Proposal_with_value_set
Manor-
An abbreviation of Manor House .. it is a building.
Stately home -
it is a building.
Fort - Fortress
A fort is a defensive structure accommodation military personal and possibly
their families.
( A castle accommodates non military personal as a priority, usually a noble
and their family with domestic staff. Then the military personal.)
Agra Fort is tagged as a barrier=wall
http://www.openstreetmap.org/way/310318567
One Castle, Krak des Chevaliers
https://en.wikipedia.org/wiki/Krak_des_Chevaliers, is tagged as a barrier=wall
http://www.openstreetmap.org/way/226877188
So .. what is the difference between a building and a castle?
A castle has a building inside a defensive wall, usually the building is
separate from the wall to enhance the building security.
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".

Past practice might be to tag the outer wall as a barrier if one exists. And
then tag the building as a building.
And that might be the 'best' solution - no separate tag for 'castle'.
This can lead to tagging the outer wall with disused, raised etc while the
inner building may still be in use.
