Is this framework compatible with Mac App Store?

[void-main]

First of all, great map kit for mac!

I'm working on an app that I wish to publish in Mac App Store. For using using OS X older than 10.9, I want to integrate your framework inside my app. And I wonder is there any chances the app using be rejected by Apple because of this framework? (For example, does this MapKit use any inner APIs? Or simply Apple doesn't like any other MapKit?)

Thanks!
