XML File for the declaration of salaries and wages

Good day
I appreciate the help I received. However, I am still in need of crucial information.
On the XML declaration file, specific codes should be used for tax exempt items. The info I received previously, didn't have these codes.
Please can someone assist? I have exhausted all possible resources.
I attach an example of some codes we do have on our system.
Thank you.
