To date, I've been ignoring the CSS 2.1 guidelines.  Just as a
motivating example, I currently have a ref file at
contributors/aryehgregor/incoming/ref-3d/green-rect.html, which
consists of

<!doctype html>
<div style="width: 100px; height: 100px; background: lime"></div>

If I read the guidelines correctly, this should really be

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
 <head>
  <title>CSS Reftest Reference</title>
  <link rel="author" title="Aryeh Gregor" href="mailto:ayg@aryeh.name"/>
  <style type="text/css"><![CDATA[
   div { width: 100px; height: 100px; background: lime }
  ]]></style>
 </head>
 <body>
  <div></div>
 </body>
</html>

I think I'm not being unreasonable when I suggest this requirement is
onerous, given that the two files render identically in all browsers
and contain essentially the same information.  Requiring XHTML 1.0
Strict may have made sense in the early days of the CSS 2.1 test
suite, but it doesn't make sense now.

I really hope no one brings up the issue that HTML5 is still in WD.  I
believe my HTML file here will work interoperably in all browsers
since probably 1998 at least, even though it happens not to have been
endorsed by any kind of specification until maybe 2005 or 2006.  XHTML
1.0 was officially standardized in 2000, but has always been and will
always be ignored by browsers for the vast majority of content on the
web, viz., files served as text/html.  Suggesting that XHTML 1.0 is
preferable because of its official standardization status rather than
paying attention to what browsers actually implement would indicate a
severely problematic attitude toward testing and interoperability.
We're here to get browsers interoperable, not adhere to process for
its own sake, right?
