    I don't think you read my post carefully enough, as your answer has no
bearing on what I wrote. There is one case in which a script-language
protocol (e.g., javascript:) is appropriate, even within an event handler,
and that is where more than one client-side scripting language is used
within a page, and even then only under certain circumstances. For instance:

<html>
 <head>
  <title>Two Script Languages on a Single Page</title>
  <script type="text/vbscript">
   Dim strTest
   strTest = "Hello, VBScript"
   MsgBox(strTest)
  </script>
 </head>
 <body>
  <p onmouseover="javascript:strTest='Hello, Javascript';alert(strTest);"
   >Pleased to meet you.</p>
 </body>
</html>
