Does Xcode's interface editor support custom properties in binding inspector?

I'm specifically talking about NSKeyValueBindingCreation. What I have to do to expose my custom properties in the Interface editor's binding inspector?

I have a simple XIB with a custom view which is subclass of NSView with optionDescriptionsForBinding: and all other methods overrides described in NSKeyValueBindingCreation. Still it doesn't work for some reason.

Is there any working example of custom NSView with exposed bindings?
