Married Filing seperately - Tax Treaty deduction

I'm a resident alien filing Form1040, while my spouse is a non-resident alien (F1 international student). We are filing separately. I'm claiming itemized tax deductions for home ownership/property taxes. According to IRS rules, both me and my spouse should use itemized deductions.

 

As a F-1 student, my wife can claim tax deduction under US-India tax treaty benefit. Will this be treated as standard deduction? Is she allowed to do this?
