xpc: suitable these purposes?

yes, xpc should work correctly between 32-bit , 64-bit processes.

why can't find in apple documentation related cross-architecture programming?

because xpc new in 10.7, , 64-bit transition guide document rather old , hasn't been updated since 10.6. apple not @ updating older documentation.
