Continuing the explorations I was making last night, this time for a 'ways to
abuse comments' section, I was working on a piece about the common use in HTML
of comments around the contents of SCRIPT elements. (It hides the content from
browsers that don't support scripts, basically.)

Here's an example HTML document that uses this convention:
<HTML>
<HEAD><TITLE>Generating Content - Or Not</TITLE></HEAD>
<BODY>
<SCRIPT LANGUAGE="JavaScript"><!--
document.writeln("<H1>Generated Content</H1>");
var todaysDate=new Date();
var message="<P>Welcome to " + (todaysDate.getMonth()+1) + "/" +
todaysDate.getDate() + "/" + todaysDate.getYear() + "!</P>"
document.writeln(message);
//-->
</SCRIPT>
<!-- // is used to hide the HTML comment closing from JavaScript-->
</BODY>
</HTML>

HTML 4.01 supports this convention - see
http://www.w3.org/TR/html40/interact/scripts.html#h-18.3.2 
XHTML 1.0 has nothing to say about this convention, even in its 'Script and
Style Elements' section (http://www.w3.org/TR/xhtml1/#h-4.8) where it
discusses
the use of CDATA sections to escape potentially difficult code.  Comments
appear not to be described at all, though they are used in examples.

I'd guess the convention has come to the end of the line, but it's not really
clear.  Thoughts?  Is the final final review period (after members have voted)
over yet?
