Expert Answer:

 fluorides gives also other parallel reaction with water with production of XeO3 (xenon trioxide):

3 XeF4 + 6 H2O -> 2 XeO3 + 12 HF + Xe  from XeO3, all other Xe compounds of oxygen are derived.

- XeO3:
In alkaline solution, it forms the XENATES (HXeO-) that give a further DISPROPORTION reaction producing Xe and PERXENATES, with oxidation number (ON) of +8 for Xe and very strong oxidants 

XeO3 + NaOH -> NaHXeO4
4 NaHXeO4 + 8 NaOH -> 3 Na4XeO6 + 6 H2O + Xe
