  var thisDocument = document;

  function func (target)
  {
    if (target.ownerDocument == thisDocument)
    {
      /* target is in the frameset document */
    }
  }

If the “ownerDocument” property was unavailable, you could compare the 
references to the root element objects by traversing the trees upwards by 
“parentNode”.

I strongly recommend not to attach vital functionality to “div” and “span” 
elements.
