Hi al-ainau,
Welcome to the community!
PayPal does not currently offer button code that validates under XHTML Strict but I know some merchants have chosen to modify the code so that it does validate.
I was able to make some changes to get a hosted add to cart button to validate under XHTML 1.0 strict.
- Removing the "target" and "border" attributes
- Making sure that all elements have a <.../> if they dont' have a separate closing tag
- Adding <p></p> to get rid of nesting element errors.

I hope this example helps to modify your own code to validate. 😄
