functional equivalent for Xonly and Xalpha

[golden]

Dear All,
    I have an question about the functionals used in ridft or dscf calculations.

In ADF, they have used Xonly and Xalpha functionals and I would like to know are they equivalence to the Turbomole's ;  slater-dirac-exchange functional and s-vwn functional ?

Is there any way to find out whether they are equivalent ?

Thanks
