Don't know about interfaces (not being a C++ or java programmer I am not sure what is meant by the term) but Simula is a OO language, with classes, inheritance, hidden and protected attributes, virtual functions. Simula is derived from AGOL 60. The first standard was Simula 67, and the latest is Simula 87. I know that it is not a well know language, but you did ask.

Are there any non Objective-C derived (or better yet, non-C-derived) languages that have this concept? If so, it would be much easier to argue for its inclusion in DocBook, even if I personally only want it for Java. :-)
