Older browsers in this case means "Netscape 2". Its safe to forget
about these days. It also applies to HTML, not XHTML. To do something
similar in XHTML you need to do something along the lines of:

      <script type="text/javascript"><!--//--><![CDATA[//><!--
        ...
      //--><!]]></script>

                      (see http://www.hixie.ch/advocacy/xhtml)

Its usually a better idea to just stick to HTML 4.01.

Its a comment, not a tag.

   White space is not permitted between the markup declaration open
   delimiter("<!") and the comment open delimiter ("--"), but is
   permitted between the comment close delimiter ("--") and the markup
   declaration close delimiter (">"). A common error is to include a
   string of hyphens ("---") within a comment. Authors should avoid
   putting two or more adjacent hyphens inside comments.

W3Schools has many errors and I generally recommend that it be
avoided. It is in no way affiliated with the W3C.

Looks about right, but I put all my JavaScript in external files. It
saves a lot of trouble.
