Need Paypal to generate error-free W3 compliant payment button codes.

[Melissa2012B]

I use https://validator.w3.org to validate the code on my site at http://DenverProcessServers.net/

If you plug http://DenverProcessServers.net/ into https://validator.w3.org and test it, you'll see the code errors in Paypal's payment button codes.

Would it be possible for Paypal to update their payment button codes and make them compliant, so that using them on my site doesn't generate errors and get my site downgraded because of them?
