Microsoft Visual Basic Scripting Edition (VBScript) does not support IHTMLDocument2::expando properties on its native language objects, nor does it cause Windows Internet Explorer to create IHTMLDocument2::expando properties on its objects. Internet Explorer supports creation of IHTMLDocument2::expando properties on its objects, in any language, through IHTMLElement::setAttribute.
In Microsoft Internet Explorer 6, this property now applies to the attribute object.
