opensuse 10.3 lamp server

This gives http 500 status:
HTML Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
  <html xmlns="">
	<title>This Does Not Work</title>
	<meta http-equiv='Content-Type' content='text/html; charset=iso-8859-1'/>

<p>Hello World</p>

If I remove the first line, the page displays. What can cause something like this?

I really appreciate any help. I am sure I have something set wrong somewhere, but have not figured it out yet.
