Where would the proposal to divide Palestine into Jewish and Palestinian states have placed Jerusalem?

Jerusalem would have been a "corpus separatum" completely outside of Israeli and Palestinian jurisdiction and under an internationally led governance. However, after ten years, there would have been a referendum in Jerusalem as to whether it would like to maintain that status quo or join with the Israeli or Palestinian State. Given that it was surrounded on all four sides by the Palestinian State, it seemed likely that Jerusalem would eventually become part of the Palestinian State through this vote.
