In the meantime I realized that if we can't use msxsl:script to implement exslt:node-set on IE, we *may* be able to use exslt:function

hmm, I wonder what gave you that idea;-)

<msxsl:script language="JScript" implements-prefix="exslt">
  this['node-set'] = function(nodes) {
    return nodes;
  };
</msxsl:script>
