[Mono-osx] Using NSAttributedString Application Kit Additions

[Jason Perkins]

Apologies for what might be an obvious question, but is it possible to access the 
NSAttributedString Application Kit additions [1]? I was looking to use dataFromRange:documentAttributes:error: in particular.

Thanks!

Jason
