Palestine Boundaries after First World War left to "the parties themselves" to resolve

From the
TREATY OF PEACE WITH TURKEY SIGNED AT LAUSANNE on JULY 24, 1923 [and published, among other places, here]:

THE BRITISH EMPIRE, FRANCE, ITALY, JAPAN, GREECE, ROUMANIA and the SERB-CROAT-SLOVENE STATE, of the one part,
and TURKEY, of the other part;
Being united in the desire to bring to a final close the state of war which has existed in the East since 1914,

And considering that these relations must be based on respect for the independence and sovereignty of States,
Have decided to conclude a Treaty for this purpose

[But it does not mention Palestine, except here:
ARTICLE I6.
Turkey hereby renounces all rights and title whatsoever over or respecting the territories situated outside the frontiers laid down in the present Treaty and the islands other than those over which her sovereignty is recognised by the said Treaty, the future of these territories and islands being settled or to be settled by the parties concerned.
