I have lots of errors on our [homepage](http://www.villasdirect.com/index.asp), and I'm working through the list, however there seems to be an issue that is difficult to get around...

I am using this for the doctype: 

```
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"

```

Which I believe to be correct, but W3 says that the attribute background doesn't exist although we have used `background="/images/blahblah.jpg"` all over the site...
