AFAIK, the only documentation is here:
https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CocoaBindings/Concepts/HowDoBindingsWork.html
but it’s extremely out of date, and was fairly hard to follow even when the screen shots matched the actual OS (somewhere around 10.4).
I’d recommend you don’t implement a custom binding at all. Custom bindings were only really useful when they were reusable in IB (that is, in Xcode 3, which supported IB plugins), because if you are doing it all in code, you may as well just write code for a two-way observation/update mechanism, without packaging it as a binding. Any custom binding you implement now can’t be used directly in IB.
