That is preferable, yes, but then you have to tell him that he must escape the
"<" and "&" characters and avoid using any "--" sequences as are so often used
in decrement operations.

Here is an example for Gene's benefit (note the &lt;)

<HTML>
  <HEAD>
    <script language="JavaScript1.2">
      <xsl:comment>
        var aname='pull';
        var NS4 = (document.layers) ? 1 : 0;
        var IE = (document.all) ? 1 : 0;
        var DOM = (parseInt(navigator.appVersion) >=5) ? 1 : 0;
        var MAC = ((navigator.appVersion.indexOf("PPC") >0) ||
        (navigator.appVersion.indexOf("Mac") >0)) ? 1 : 0;

        //global nav
        function ShowLayer(){return};
        function OutLayer(){return};
        if (document.layers) {
          appVer = navigator.appVersion.substring(0,4);
          if (appVer &lt; 4.06) NS4 = 0;
        }
        if (NS4 || IE || DOM) globalPulldown = 1;
        if (!globalPulldown) event = null;
        //</xsl:comment>
  </HEAD>
  <BODY>
  ...
  </BODY>
</HTML>
