That's what the '/' at the end of the tag is for.  Shorthand HTML I
guess.  It's valid html, but in some cases just less readable.

And what's weird is the <span></span> format seems to have parsing
issues when between 'script' tags.  The following does not seem to
parse properly:

<html>
<head></head>
<body>

<script tal:define="USER_NAME user/getUserName"
        type="text/javascript">  
function connect()
  {
    username = <span tal:replace="USER_NAME">username</span>;
  }
</script>

</body>
</html>

Error Message:
Compilation failed
TAL.HTMLTALParser.NestingError: Open tags <html>, <body>, <script>
do not match close tag </span>, at line 8, column 54

Getting rid of the 'script' tags fixes it, but does not solve the
original problem.
