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.

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.
