for a desktop application I am developing, I have to stick with a 32-bit framework. I am looking for the best path to run the framework in its proper process and develop the rest of the application in a 64-bit process. The application is also meant to be sold in the AppStore, so it should support Apple sandboxing.

I am thinking about XPC: is it suitable for these purposes? Why can't I find it in the Apple documentation related to cross-architecture programming?

XPC: is it suitable for these purposes?

Yes, XPC should work correctly between 32-bit and 64-bit processes.

Why can't I find it in the Apple documentation related to cross-architecture programming?

Because XPC is new in 10.7, and that 64-bit Transition Guide document is rather old and hasn't been updated since 10.6. Apple is not always good at updating older documentation.
