Except when it doesn't.

For example, here's a fragment of hotmail.com's signup page, served as
"text/html".  It's the only example I've come across to date:


<!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" dir="ltr">
...
<select id="iRegion" name="pff00000000010004" />
  <script>...</script>
</select>
...


The script just document.write's loads of option tags (it's the country
menu).  It's hard to know what the author thought was going on.  Did they
think it was XHTML and just got stymied by the server configuration?

I'm still in favour of permitting the trailing slash, personally.
